This month we present you with information about the warm and inviting gemstones of the fall. This season evokes the beautiful colors of the falling leaves. The beautiful oranges, burgundies, and yellows conjure up many feelings and memories of fall leaves, sunsets over the mountains, pumpkins and cornucopias. In celebration of autumn, we take a moment to appreciate some fall-hued gemstones, courtesy of the experts at the Gemological Institute of America (GIA).
Citrines are a variety of the mineral quartz crystals commonly found in igneous, metamorphic and sedimentary rocks. Citrines are commonly found in shades of yellow, but they can appear in an orange shade called Madeira.
Citrine is the gemstone for the zodiac sign of Scorpio, and the gemstone given for the 13th and 17th wedding anniversaries. In ancient times, citrine was worn as protection against bad skin, evil thoughts, snakebites and even the plague. Mined mainly in Brazil, citrine is often found in larger sizes, due to its affordable price, and it is easy to find.
Fancy sapphires are a variety of the mineral corundum, and come in orange, as well as other colors. An especially alluring orange-pink color is called padparadscha, after the lotus blossom. According to GIA gem experts, padparadscha are very rare and range from pastels to more fiery shades of orange.
The finest authentic padparadscha sapphires are usually very expensive, on par with their blue counterparts. Sri Lanka and East Africa are two major sources of orange and padparadscha sapphires.
Fire opals are known as an anomaly in the gem world. Mined in Australia, opals are usually smoothly polished in a cabochon (domed) shape and are opaque (not see-through). But the fire opal is often found in a fantastic orange color, cut in a faceted manner, and is mostly transparent in better quality facet-grades.
Spessartine garnet is one of the most appealing of all the orange-hued gemstones. According to GIA’s colored stone experts, it is prized for its bright orange-yellow to yellowish-orange color, with some of the best — and most sought after — examples mined in Southern California, at the Little Three mine, near Ramona. High-quality spessartine has more recently been mined in Namibia and Nigeria.
Mandarin garnet is also known as bright orange spessartine. Found in Namibia in Southern Africa, the rich color of the Mandarin garnet makes it a popular choice with orange gemstone lovers. Although relatively inexpensive in small sizes, larger stones—which rarely exceed 10 carats — can be very expensive.
Topaz gems are another gemstone found in various colors, including yellow, dark blue, pink, red, and light green, but they truly glow in orange. Fine orange and “imperial topaz” (orange with a hint of red) are among the rarer colors of topaz, and their higher prices reflect their scarcity. This unusual shade is mostly found in Brazil.
Whatever type of gemstone you prefer, keep in mind that there’s no right or wrong when choosing. The important thing is to do your research on the particular gemstone that you like, and look for a jeweler. Make sure the appraiser is educated by the GIA (Gemological Institute of America), ensuring professional expertise in the valuation of our fine gems and precious metals. Also make sure the pawn shop or jewelry store is a member of the National Pawnbrokers Association.
If you are looking to update your jewelry wardrobe for the season, or to purchase fine jewelry as holiday gifts, you’ll find fine estate, vintage and antique jewelry visit Adina’s eBay store. You’ll discover authentic fine jewelry at true wholesale prices, authentically appraised by GIA-trained experts.
October Birthstone: The Opal
October’s birthstone is one of the most interesting gemstones on earth. In celebration of the magical and mysterious opal, let’s take a look at some fascinating and rare facts about the origin and value of opals.
The first opals are believed to have been found in Ethiopia about 4,000 BC. The ancient Romans called the opal “Cupid Paederos,” which translates to “a child beautiful as love.” The ancient Romans would grind up and consume opals because they believed they had healing properties and the power to ward off bad dreams.
The term opal is derived from the Sanskrit term “upala,” which means precious or valuable stone and the root for the Greek term “opallios,” which translates to “color change.” Opals are created from an ancient mineral known as petrified silica gel that is found near the earth’s surface where geothermal hot springs once existed.
Today, about 97 percent of the world’s opals come from Australia. The first Australian discovery of common opals was made in 1849 near Angaston, South Australia by a German immigrant named Johannes Menge. The indigenous people of Australia call the opal “the fire in the desert.” Most of the world’s supply of precious opals comes from the Coober Pedy and Andamooka fields in South Australia. Coober Pedy is known as “The Opal Capital of the World” because 51 percent of the world’s supply of opals is mined there.
Opals may come from other planets as well. In 2011, scientists discovered opal-like crystals in the Tagish Lake meteorite, which fell to Earth in Canada in 2000. According to a report in the Journal of the American Chemical Society, this was the first extra-terrestrial discovery of these unusual crystals. Some scientists hypothesize that they may have formed in the primordial cloud of dust that produced the sun and planets of our solar system 4.6 billion years ago.
The classes of opals
All naturally occurring opals fall into one of two classes: precious and common. Precious opals are those that display flashes of iridescent colors when turned and tilted, and light strikes its surface at various angles. This effect is called “play of color,” but is scientifically referred to as opalescence.
Play of color, or opalescence, is caused by tiny sphere formations of silicon which make up the structure of opal. When light is refracted by the spheres, it causes light to be separated into its various spectral colors. The actual colors being emitted are controlled by the size and distance of the spheres to each other.
While opals come in many diverse colors and combinations, precious black opals are the most valuable and in demand because of their rarity and play of color. Precious opals also come in white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, and brown. Reds against black are most rare, while white and greens are the most common.
Any opal that does not exhibit “play of color” is classified as a common opal. Common opals are classified as non-gem quality opals. There are several varieties of common opal and most are opaque. Common opals, sometimes called “potch,” are usually colorless or white, but may also come in gray, brown, yellow, or red.

It has been 20 years since the passing of Princess Diana, and her legacy is remembered by the world as strongly today as it was two decades ago. Kept forever in our hearts for her humanitarian efforts and grace, her style was also influential in fashion as well as jewelry.
Case in point was the unusual choice of her engagement ring. In 1981, Princess Diana chose the ring for her engagement to Prince Charles. She was criticized at the time for choosing a ring that “anyone could buy” instead of having one custom made. But Lady Di had an eye for style, and replicas of the ring were quickly in demand, as they are again today. The royal ring was originally purchased in 1981 from the catalog of the historic British jeweler, Garrard, for 28,000 British pounds ($65,000 USD). Today, the ring is said to be worth about half a million dollars, with the sapphire alone worth $300,000. Princess Diana liked the ring so much that she even wore it after her divorce from Charles.
Upon Diana’s death, both of her sons chose a keepsake of hers — Prince Harry chose his mother’s engagement ring, while Prince William chose his mother’s gold Cartier watch. But the two brothers had an agreement that whoever became engaged first would present the ring to their betrothed. Prince William romantically proposed to his sweetheart of over eight years, Kate Middleton, while they were on vacation in 2010 in Kenya. Prince William proposed to Middleton with the famous sapphire and diamond ring, stating later he used his mother’s engagement ring as a “way of making sure my mother didn’t miss out on today and the excitement.”
Diamonds and Sapphires
The royal engagement ring is a deep blue oval sapphire — estimated at 12 carats — encircled by 14 round diamonds set in 18K white gold. After her engagement, Middleton had the engagement ring resized by the royal jewelers G. Collins & Sons to fit her finger better. She asked them to attach small platinum beads inside the bottom of the ring to make it smaller. When Middleton first showed the ring in public at St. James’s Palace in London, she wore a royal blue dress by Issa that accentuated the blue of the sapphire.
Royal Replicas In Demand
Soon after Kate Middleton first appeared wearing the royal ring, demand for replicas skyrocketed around the globe as it did when Diana first appeared wearing it. The National Sapphire Company’s website actually crashed from demand-related traffic and jewelers around the world worked overtime to respond to the demand.

Healing Properties of Popular Gemstones
For centuries, people have believed in the healing qualities of crystals and gemstones; not surprisingly, as they are among the oldest natural objects on earth. Here’s a quick guide on the healing qualities of 10 popular gemstones.
Whether or not you believe in their magical powers, gems are beautiful items with significant meanings. Here’s a quick guide to the healing qualities of 10 popular gemstones, courtesy of eluxemagazine.com.
Where crystals come from
Healing stones, crystals and semi-precious gemstones come from one core source — the Earth. Created from the magma from the Earth’s inner core, these stones have been heated, cooled, and are often amongst the most ancient objects on the planet.
Every stone is made up of tiny crystals which are in constant motion, so they do indeed emit an energy signature or frequency. In addition, their striking colors can influence our moods and emotions, so it makes sense that many people believe in the healing energy of gems.
History of healing
Historically, people have had strong connections to gems for many reasons. Evidence of gemstones used for healing has been found as far back as 4 BC. Ancient civilizations such as the Chinese, Egyptians, Sumerians, Greeks, Romans, and more modern shamans and medicine men have used gemstones for healing in multiple ways — they’ve ground them into powders or elixirs, worn, carried or placed them on the body and in ceremonies or rituals. It’s said that rough gemstones, broken or mined from a rock, are most powerful–some healing therapists believe that these can be placed gently on the body to transmit and focus healing energies.
1. Turquoise: Turquoise can be a very powerful stone for protection. It increases inner calmness and eases depression, fears, exhaustion and anxiety. It is a stone for friendship and love. Turquoise has calming effects when speaking in public. It helps us to express ourselves and aids in creative problem solving.

2. Amethyst: Amethyst is a very powerful crystal for calming and stress reduction. It is known to calm and bring clarity to the mind, to relieve stress, sooth sadness, anger and anxiety and balance mood swings.

It can be utilized to bring light and energy into our spiritual bodies. It enhances mental abilities and can be ‘programmed’ and imprinted with any desired energy or information. Crystal quartz is powerful for protection and amplifies positive energy and thought. Due to its power to open up all chakras, it is a great stone for relaxation and also to be combined with other stones, as it amplifies their powers.
5. Moonstone: Moonstone aids in inner growth, strengthens intuition, and stabilizes emotions. It is known as a stone for new beginnings, success in love and business, and good fortune. It promotes inspiration and protects us, especially those of us who are very sensitive. Moonstone is said to perceive that which IS, making it a very personal stone. It is a great aid for meditation and helping us to understand ourselves. Moonstone also soothes stress and anxiety. This beautiful stone is particularly beneficial for women, especially young women, in helping them connect with their feminine side. Moonstone is also said to have the power of making wishes come true.
6. Onyx: Onyx is an excellent stone for stressful or challenging situations as it gives us strength and support. Its soothing qualities alleviate fear and worries and encourage wise decision-making. Onyx is known to increase happiness, intuition and good fortune. It is known to help us change bad habits and keep emotions under control. Onyx helps us to focus and stay grounded. Onyx is also known to help with skin ailments, infections and inflammations. This stone needs to be cleansed and recharged regularly — wash it in salt water or pass it through incense smoke.

As an extra bonus, rose quartz is said to reduce wrinkles, and is also known to be a protective stone during pregnancy, protecting from miscarriage.
8. Citrine: Citrine is known as the stone of the mind, stimulating the brain, increasing concentration, strengthening the intellect, and increasing psychic powers. It promotes clarity of thoughts, opens the mind to new thoughts, and brings relief to nightmares. Citrine is believed to invite wealth and prosperity into your life. Due to its qualities that bring abundance, citrine has been called the “Lucky Merchant Stone” and business owners place it into their cash drawer to increase sales.

Whether gemstones have healing powers or not, if you’re looking for fine gemstone jewelry, look no further than Adina Jeweler’s eBay store. You’ll find a gorgeous range of fine estate, vintage and antique gemstone jewelry at true wholesale prices.
For many, summer is the ideal time to scour yard and estate sales for interesting fine jewelry pieces. There are great finds out there, but it’s sometimes difficult to know what you’re looking at—unless you know what you’re looking at. Here’s an overview of the definitions and differences between estate, vintage, and antique jewelry.
Estate, vintage, and antique jewelry have similar meanings but the differences between them can greatly influence the value of the jewelry pieces. Before you purchase a previously owned piece of jewelry, it’s important to know the differences.
Estate jewelry: an umbrella term
In general terms, many people consider estate jewelry to be any piece of jewelry that has been passed down from a previous generation, but it actually refers to any piece of jewelry that was previously owned, regardless of its age.
Estate jewelry can be broken down into two types: vintage jewelry that is less than 100 years old and antique jewelry that is more than 100 years old.
For more on the difference between vintage and antique jewelry, we reference about style.com’s jewelry article, “What is the Difference Between Antique, Vintage, and Estate Jewelry?”
Vintage jewelry: Less than 100 years old
Vintage jewelry has to be at least 20 to 30 years old, and created between 1910 and 1990. Vintage is probably the most common term of the three, since it encompasses a large collection of jewelry ages.
The most commonly collected are vintage pieces from between 1940 and 1970. That includes the glamorous, Hollywood-inspired 1940s jewelry, the fabulous Jackie Kennedy-inspired jewelry of the ‘60s, and even the bold jewelry of the1980s.
Jewelry eras within vintage include: Modern, Mid-Century Modern, Retro, and Art Deco.
Antique jewelry: More than 100 years old
Antique jewelry is any piece of jewelry that is at least a century old. So, by definition, all antique jewelry is considered vintage, but not all vintage jewelry is considered antique.
When shopping for antique jewelry, beware of the term “antique style,” which is a tip off that the piece is not really antique, but rather made in the style of older, antique jewelry.
Anytime the word “style” is used when describing a piece of jewelry that appears to be old but there is no other mention of the item’s age, this most likely means the item is a reproduction.
Many pieces from the 1920s are now considered antique, especially those made in the earlier part of decade. Jewelry eras included in antique jewelry are Art Deco, Edwardian, Belle Epoque, Art Nouveau, Victorian, and Georgian.
It’s important to remember that the use of the terms estate, vintage, and antique can be confusing, and in some cases misleading, so it’s very important to understand the differences to avoid accidentally buying a reproduction piece. Of course if you’re looking for a less time consuming way to find fine estate, vintage and antique jewelry visit Adina’s eBay store. You’ll find fine jewelry that’s already been appraised by GIA-trained experts at true wholesale prices.
Father’s Day is Sunday, June 18. Here are some cool and classic jewelry gift ideas to help show the father figure in your life how you really feel about him.
History of Father’s Day
Let’s first start with some history of the holiday. Created in 1910 by Sonora Smart Todd, her idea was to create a day to complement Mother’s Day, which had been established in 1908 by Ann Jarvis. Although it would take almost two decades for the holiday to gain popularity, it eventually took hold, as we still celebrate it today.
A piece of jewelry to cherish
To really impress the dad in your life, you may want to consider giving a piece of jewelry, such as a watch, tie clip, or cuff links. As jewelry designer David Yurman said, “I’ve always felt that jewelry is one of the most personal and emotional gifts you can give your loved one.” Men really do appreciate a good piece of jewelry as much as women do, especially if it’s wearable and practical, in addition to being beautiful.
A timeless watch – Watches are truly a unique statement about the wearer. If you’re considering giving a watch, take a moment to think about your father’s personality. Is he classic and conservative, or edgy and cool? Is he active and in need of a durable sports watch? Or tech-savvy who will appreciate a smartwatch that is an extension of his iPhone? If so, then consider the Apple Watch Sport or a host of other iOS-compatible smartwatches on the market.
Depending on your budget, if his taste leans toward classic styles and higher end brands, a fine watch can become an heirloom that is handed down for generations. Before you spend more than you should, read 6 Things to do before Buying a Rolex.
A unique necklace — Like a watch and most pieces of jewelry, a necklace should really speak to your father’s personality and taste. Consider a pendant that reflects his personal beliefs, likes and interests. Is he a religious man? How about a nice gold cross or pendant with the Hebrew Life sign? Or a guitar if he’s a musician; or maybe a dog tag proclaiming your love for him. There are some unique options out there, including a Batman logo with the saying, “You are my superhero.” Take time to investigate and you’ll be sure to find the perfect piece.
A pair of classic cufflinks — Few pieces of men’s jewelry say class and elegance like a pair of gold or silver cufflinks. Prices range widely for cufflinks, so don’t be intimidated. A basic pair of stainless steel cufflinks generally starts around $20.00 and increase into the thousands, depending on the metals and gemstones attached to them. Go the extra step and have them monogrammed with your father’s initials.
Whatever you decide to give to your dad on Father’s Day, remember that time is the most precious gift of all, so if you can, spend Father’s Day with your dad doing something he likes. Or take time to reminisce and remember him with family. Happy Father’s Day to all the dads out there!
Planning on buying a diamond engagement ring? This can be an intimidating task if you don’t know how diamonds are rated and valued. Here’s a review of the 4Cs—cut, color, clarity and carat—as well as some other diamond buying tips to help you feel confident when you browse and buy.
The GIA Diamond Rating System, aka the 4Cs
In the 1940s, the Gemological Institute of America (GIA) created a universal rating system to standardize the diamond rating process, and ultimately protect consumers from getting ripped off.
Known as “the 4Cs,” the GIA International Diamond Grading System™ is the jewelry industry standard to objectively evaluate, compare, and rate diamonds.
Carat—the standard unit of weight. The word carat derives from carob seeds because early gemstone appraisers used carob seeds as counterweights on their scales.
One carat weighs 0.2 grams, and one carat is equal to 100 points. Therefore, a quarter carat weighs 25 points, a half carat weighs 50 points and a three-quarter carat weighs 75 points. It takes about 142 carats to equal one ounce.
A fraction of a carat can mean a big difference in the value of a diamond, so precision in measuring is crucial. Carat weight is often measured to the hundred thousandths of a carat, and rounded to a hundredth of a carat.
Note: Diamond carat should not be confused with gold karat, which refers to gold purity.
Color—colorless is more valuable. Diamonds are valued by how closely they approach colorlessness: the less color a diamond has, the higher its value. The exception to this rule are the rare colored diamonds—known as “fancy” colored diamonds—which are growing in popularity. Most diamonds sold in retail stores are near colorless to faint or light brown or yellow.
The Gemological Institute of America’s universal color scale starts at D, representing colorless, and goes through Z and beyond to the fancy and vivid colors. The higher the letter, the more presence of color in the diamond.
Clarity—a diamond’s internal and external flaws. Blemishes are external flaws, and inclusions are internal flaws. Inclusions are created when the diamond is formed, or when the diamond is cut. Because 100 percent “perfect” diamonds are very rare in nature, those with fewer blemishes and inclusions are rarer and cost more.
The GIA International Diamond Grading System™ Clarity Scale is the standard clarity grade scale, and contains 11 grades. Diamonds are assigned a clarity grade ranging from flawless (FL) to diamonds with obvious inclusions (I3). Most diamonds are graded in the VS (very slightly included) or SI (slightly included) categories.
To determine a diamond’s clarity, appraisers using the GIA Clarity Scale consider different variables, including the diamond’s size, nature, position, color or relief, and quantity of clarity characteristics visible under 10X magnification.
Cut—rates characteristics of shape. The GIA system rates a diamond’s cut using five grades: Excellent, Very Good, Good, Fair, and Poor. The system considers factors such as brightness, fire and scintillation, weight ratio, durability, polish, and symmetry.
The cut of any diamond has three attributes: brilliance (the total light reflected from a diamond), fire (the dispersion of light into the colors of the spectrum), and scintillation (the flashes of light, or sparkle, when a diamond is moved).
Most diamond jewelry uses the standard round brilliant shape. All others are known as fancy shapes, and include the marquise, pear, oval, and emerald cuts. Diamond shapes such as hearts and triangles are also gaining in popularity.
Other Important Diamond Buying Tips
Understanding the cut, color, clarity, and carat of a diamond is important, but when it comes down to it, choosing the right diamond is also subjective: how you feel and what you like. Don’t just focus on the GIA rating—go with a diamond that looks beautiful to you—or better yet, your mate will appreciate—and is in your budget. Make sure you know the person’s taste and ring size, as well as the jewelry store’s return policy.

In celebration of April’s birthstone, the diamond, we’re sharing an interesting new discovery about diamonds, courtesy of Michelle Graff and nationaljeweler.com.
In February, the Lucapa Diamond Co. in Perth, Western Australia announced that it has discovered the largest recorded diamond ever found in Angola: a 404.2-carat stone that has tested as Type IIa and D color.
The diamond was recovered from Alluvial Mining Block 8 at Angola’s Lulo Mine, which has produced more than 60 large, special diamonds since they started mining there just last August.
The company reported that the 404.2-carat stone is the 27th largest recorded diamond in the world, and the biggest diamond ever discovered by an Australian mining company. It also is the fourth 100-plus-carat diamond to be recovered from Lulo to date, as well as the 114th largest “special” diamond–meaning it weighs more than 10.8 carats–recovered from the mine.
Of further interest is the scientific work that geologists are doing on the unique properties of large Type IIa diamonds similar to the ones being found at Angola’s Lulo Mine.
Evan Smith, a postdoctoral research fellow at the Gemological Institute of America specializing in diamond geology, and his colleagues are trying to better understand Earth’s mantle, which is beneath tectonic plates and, as such, largely inaccessible for scientific observation.
As you may already know, Type IIa diamonds have very little to no nitrogen, which is what makes white diamonds so exceptionally colorless and fancy color diamonds so vibrant. Large Type IIa diamonds that make headlines also tend to be irregular in shape, rather than the nice, symmetrical octahedrons like so many smaller stones. They often have a surface that’s rounded and somewhat dissolved, “almost like a lollipop after someone’s been after it for a while,” says Smith.
The fact that these big, beautiful diamonds are different has not escaped the attention of earth scientists, who have wondered for years if they form in a different way, in a different part of Earth’s mantle, and thus tell us something different about our planet.
In order to conduct the study, though, Smith and the other researchers could not limit themselves to these kinds of large and exceedingly rare diamonds. Instead, they studied Type IIa diamonds of all sizes that came through the GIA lab, including some that were smaller than a carat.
After examining 52 Type IIa stones (and one Type Iab) of all sizes at the GIA lab, Smith and the other researchers found that in nearly three-quarters of the diamonds (38 out of 53), the inclusions weren’t graphite but metallic, a solidified mixture of iron, nickel, carbon, and sulfur.
This is significant because it changes the way scientists think about how different elements, like carbon, nitrogen, and sulfur, are distributed. It also has broad implications for understanding the behavior of the deep Earth, including the recycling of surface rocks into the convecting mantle.
Smith said this discovery verifies what geologists have been theorizing for 10 or more years: that the Earth’s deeper mantle environment has a “light peppering” (up to 1 percent) of metallic iron.

Are you looking for a watch? How do know an estate watch’s value? With the growing trend of wearing wrist watches again, many are looking at estate, vintage or antique watches. If you’re looking to find out how much a watch is worth, there are a number of factors that go into evaluating it. Here’s an overview of what makes a watch valuable.
Condition of the watch.
The condition of the watch is extremely important in appraising its value. A watch will be worth much more if all of the parts and movement are original. There should be no changes to the face of the watch. Any scratches, dents, chips, or rust will obviously lower its value.
Inside of the watch.
What a watch looks like on the outside is only part of the evaluation. The watch appraiser will look inside to see the internal movement of the watch and to make sure it’s working or can work, and if the mechanism parts are original. Also important is the number of jewels used in the mechanism. Generally the greater the amount of jewels, the better the movement.
The manufacturer and brand.
If a watch is by a famous or rare name brand, or from a well-known manufacturer, it’ll usually command a higher price. Within the watch should also be serial or model numbers to confirm its authenticity.
Its design and composition.
Craftsmanship and design matters. Intricate designs, enameled or hand painted designs, and inlays of precious stones will make your watch extremely valuable. An antique or vintage watch in solid gold or platinum, especially with an original band in good condition, will greatly increase the worth of the watch. If the watch is truly gold, it will be stamped 14k, 18k or 750 (the European designation, meaning 75 percent gold).
Gizmos and gadgets.
Watches that have unusual displays such as moon phases, timers, stop mechanisms, and/or show month date and day are of interest to collectors and will raise the value of the watch.
The watch’s age.
Although the quality of the watch’s condition is usually more important, the age or historical value of the watch is also a consideration.
Finally, a less scientific factor influencing a watch’s value is whether or not it is in demand. If a watch is in demand, it will fetch a higher price.
Before you buy.
If you’re interested in buying an estate, vintage or antique watch take note of any logo, markings, serial or model numbers as well as metal stamps indicated on the watch.
Then, do some research online to find a reputable jeweler with a specialty in fine watches and ensure it comes with an accurate appraisal. If you’re in doubt, get an appraisal by a professional jeweler who specializes in watches who will provide you with the most accurate estimate of what your watch is worth.
If you’re looking to buy an estate, vintage or antique watch, shop with confidence at Adina’s eBay store where you can rely on the experts at Adina. You’ll find fine a vast selection of fine watches at true wholesale prices and deliver a buying experience that’s above your expectations
If you’re in the market for jewelry, it’s best to pick up some tips from the experts before you buy online. With faster Internet speeds and increased e-commerce security, buying jewelry online has steadily increased by the year. Falling diamond prices and high numbers of jewelry store closures have contributed to the trend.
But jewelry can be particularly tricky to buy sight unseen. With Valentine’s Day around the corner, here’s some expert advice on how to buy jewelry online, courtesy of former jewelry store owner, Clancy Martin on vice.com.
Don’t buy jewelry as an investment.
Before buying any expensive piece of jewelry, know in advance that it is not likely to become an investment. The piece may increase in value if it’s a rare, excellent stone, but don’t go into buying hoping it will increase in value. Buy it because you want a luxury piece of jewelry to enjoy, like a luxury car.
All colored stones are treated.
According to Martin, there is simply no such thing as “natural”-colored gemstones, especially if it’s been set in a piece of finished jewelry—a piece that has been completely assembled.
He also suggests avoiding stones that have been irradiated or injected with colored glass or silicon, which is one of the most popular treatment techniques, especially for expensive rubies and sapphires.
The only way to guarantee that the stone you are buying has not been treated in this way is to be sure that you can return the stone after having it appraised by an independent expert.
Natural pearls are extremely rare, he explains, and buyers should insist on a certificate guaranteeing their authenticity and only buy from an established business that specializes in natural pearls.
When shopping for colored gems and diamonds, know that irradiated and synthetic stones are now the norm, so insist on full disclosure in writing from the seller about how the stone acquired its color. Once you receive the stone, have an independent appraiser test the stone to be sure that the disclosures are accurate. If they are not, return the stone. This may also give you leverage in price.
A hallmark can be forged.
Be warned that a hallmark, such as a stamp of karat weight, metal type, or of a designer’s signature, is easily faked. Anyone can make a stamp that says Pt (for platinum, stamped on white gold), 18k (stamped on 14-karat gold), or JAR (Joel A. Rosenthal). Martin advises that buyers always and only purchase 18-karat gold or platinum. Be on guard especially if you’re shopping for a one-of-a-kind piece, such as a Louis Comfort Tiffany, Fabergé, or Cartier.
The problem with buying online is that you can’t inspect the piece in person under a loupe. If you can’t see the physical piece, then be sure to shop and buy from the official manufacturer’s website. You’ll likely pay more, but at least you’ll know it’s an authentic piece. In any case, ask about “proof of provenance.” Do what you can to find out about the history of the piece, such as where it came from, how are they certain it’s original, etc.
Certificates can be faked.
Like a hallmark, keep in mind that any certificate of “authenticity” can also be faked, including the Gemological Institute of America (GIA) and the American Gem Society (AGS), as well as “Kimberly Process” papers and conflict-free papers—and any such warranty should always be checked with its issuing agency.
Buy significant diamonds loose or unmounted.
When it comes to buying a significant diamond, Martin advises only buying “loose” or unmounted stones—but be sure to educate yourself first. A sophisticated diamond buyer understands how important an excellent cut is to the value of a diamond, such as make and proportions. Take the time necessary to learn about and appreciate the nuances of diamond cutting. Online video tutorials can help.
Bargain, bargain, bargain.
Whether you’re buying online or in-store, try and get the best deal you can, especially on an expensive piece of jewelry. Martin says you must be shameless in bargaining. It doesn’t matter whether you’re buying from Cartier or Neiman Marcus or De Beers or Barneys or Graff; or if you’re spending $1,000 or $100,000. Offer less then they’re asking; shop around; wait for sales. The more time you are willing to invest, the more money you will save.
Never buy a used Swiss watch.
Forgery has become rampant in the Swiss-watch business, and even the experts may be hard-pressed to tell the difference. So if you want to be sure, buy from a manufacturer’s official website and/or registered dealer. Again, bargain. Depending on the brand, you should demand a 40-percent discount from the sticker price; a 30–35-percent discount on most popular brands like TAG Heuer, Cartier, and IWC; and a 20–25-percent discount on the most desirable brands like Rolex and Patek Philippe.
In summary, do your due diligence. The more you plan on spending, the more time and effort a buyer should invest in the purchase. Martin suggests looking at the process like a game or hobby—the more you learn, the more fun it is to buy, and the better deal you will obtain.
