The Mother of Female Jewelry Designers

For centuries jewelry was designed by men.  Seems odd, doesn’t it, when most all jewelry is worn by women?  But the design field was male dominated for the same reason most fields were–men were seen as the more capable sex and the bread winners of the family.  When did it become clear that women could design for women?

Perhaps the first to recognize this talent in a female was Rene’ Boivin, a Parisian goldsmith and engraver in the late 1800s.  He married Jeanne Poiret, a woman who became his business partner in his jewelry workshops.  Together they created fabulous designs which were in high demand among their elite clientele.

When Rene’ died in 1917, everyone assumed that Jeanne would sell the business but, instead, she and her daughter, Germaine, assumed control.  Jeanne, though not trained as a jeweler, knew a lot from working with her husband.  She’d think out the designs and have someone else render them. She also had a talent for finding good talent, hiring young Suzanne Belperron in 1921 and, when Suzanne left in 1931, the talented Juliette Moutarde took her place.

Suzanne Belperron opened her own jewelry design firm with Bernard Herz, and later, his son, Jean, in a partnership that lasted over 40 years.  Her designs were so distinctive–very fluid and organic.  Even while those around her embraced Art Deco, with its straight lines, Suzanne elevated a more modern design.  Famous women like the Duchess of Windsor and Mona Williams (pictured below) bought her jewelry.  Her work was never signed, though.  She always said that her style was her signature.

Juliette Moutarde worked with Jeanne and Germaine at House Boivin until they sold the company in 1976.  Jeanne had died in 1959, but her daughter, a talented jewelry designer in her own right, kept the business going.  Throughout these successful years, custom pieces were never signed by the individual artists.  Perhaps it was seen as too bold, too assertive, for a woman to sign her work back in the early 1900s.

But because of these women, and a few others like Italian Elsa Schiaparelli, female jewelry designers today feel empowered to open their own studios, sign their names to their pieces, and earn their own success in the design world. Thanks to these pioneers, we know names like Paloma Picasso, Elsa Peretti, and Ippolita Rostagno, who have had their own jewelry lines for decades.  And because of THEM, contemporary female designers–from Kendra Scott and Irene Neuwirth to Farah Khan Ali and Erica Courtney find success in the always competitive jewelry industry.

Today we don’t think much about gender when choosing a designer.  If you like the creation, you respect the designer!  But it wasn’t always like that, and I wanted to lift up the courage of Jeanne Bouvin and her team of female designers.  They worked and made their way successfully in a male world.  Good for them and thank goodness for us.  Their combination of talent and determination allowed women who came after to enter the field with confidence.  Because of that, I want to nominate Jeanne Poiret Boivin for Mother of Female Jewelry Designers!

Back in Business with Burma

| November 10, 2016 | Reply

I’ll never forget vacationing in Thailand, trying to decide whether to buy a pair of jadeite earrings.  The beaming salesman chanted to me, “Burmeeeese jade,” with a knowing nod. His smile implied that nothing could be better.

That was about eight years ago, when jade and rubies from Burma (Myanmar) were banned from the United States.  Retailers in the U.S. could not sell them.  Wholesalers could not import them.  Well, that recently changed, and the announcement got me interested in the story of how these gems came to be sanctioned.

It was back in 2003 when George W. Bush signed the trade embargo, prohibiting the import of Burmese goods.  The military ruling group, the “junta”, of the country had imprisoned the people’s leader, Aung San Suu Kyi.  Citizens of the country were having their human rights violated.  The embargo was a response to what was considered an unacceptable way to govern.

But there were loopholes in the 2003 document, and Burmese jade and rubies still found their way into the U.S.  If a “middleman” country got involved, either in the cutting or polishing step, it was still legal to import these gems to the U.S.  That is, until July 2008.

President Bush signed a new document, the Tom Lantos Block Burmese J.A.D.E.(Junta’s Anti-Democratic Efforts) Act, which closed the loopholes and effectively banned the import of ALL precious Burmese gemstones.  Wholesalers and retailers selling ruby and jade needed documentation to certify that the gems had not originated in Burma.

The jewelry industry was negatively impacted by the embargo.  Burma was considered the best source in the world for fine ruby and jade.  Different sources of the gems had to be found, and, over the years, they were.  Today many rubies come from Mozambique. Jadeite sources include Guatemala, Japan, and Kazakhstan.

The trade sanctions had the desired effect.  Myanmar began to make reforms in 2010. Over the next couple of years, democratic elections were held and many political prisoners were released.  In 2011, the U.S.  appointed an ambassador, and, in 2012, President Obama visited the country.  Using a cautious approach, President Obama lifted some of the sanctions in November 2012.  But the ban on rubies and jade remained in place.

Aung San Suu Kyi, who is now the nation’s State Counsellor (sort of like a Prime Minister), expressed patience, saying that “We believe that if we are going along the right path, all sanctions should be lifted in good time.”  And she was right!  On October 7th, 2016, President Obama signed an executive order to lift the remaining trade sanctions against Myanmar.

It will be interesting to see how this executive order influences the jewelry industry in the coming months and years.  It will take some time to establish or re-establish relationships with Burmese stone dealers.  But I believe it won’t be long before we see the deep blood-red Burmese rubies back in our stores.  And my “Burmeeeese” jade earrings (Yes. . . I bought them) may soon be easy to find in the United States.

History of Birthstones

Garnet: January birthstone

Most of my life I’ve wished I was born a few days earlier, mainly because my birthstone would be an emerald instead of pearl or alexandrite.  When it came time to buy my high school class ring, I chose the emerald green stone rather than the pale purple one.  When my husband and I designed our 30-year anniversary ring, we designed it with an emerald for the center stone, even though pearl is the traditional gift for the 30-year anniversary.  As you can see, I’ve always just gone with what I wanted rather than what I was ‘supposed’ to want.  But my decisions got me to thinking about the origin of birthstones.  Who deemed that each month be represented by a different gemstone?  When was this decision made?  And why?

My research on these questions has revealed an interesting and somewhat nonsensical journey.  Most sources say that the idea of birthstones started with the Bible and Aaron’s breastplate.  Aaron had 12 stones in his breastplate, representing the 12 tribes of Israel.  No one knows for sure what the 12 stones were, but chances are high that they were pretty rocks, like jasper or lapis.  These are rocks that were native to the area.

A first century historian named Josephus supposedly made the numeric connection between the 12 stones and the 12 months of the year.  For centuries the idea was to have 12 stones, carrying a different one each month.  They weren’t really birthstones because they weren’t associated with the owner’s birth.  They were associated with months of the year.  The individual stones were supposed to bring good luck and good health during each one’s specific month.

But somewhere along the way, the idea changed.  Experts say that between the 15th and 18th centuries, people began to see themselves as having one stone, corresponding to the month of their birth, that would bring them good fortune.  These stones, with a few exceptions, are very different from the birthstones of today.  Have you ever heard of bloodstone?  It’s an opaque green stone with red spots.  It was the birthstone for March.  How about sardonyx?  That’s a banded, rusty brown-colored, translucent chalcedony that was the birthstone for August.

Bloodstone: March birthstone

Bloodstone: March birthstone

Sardonyx: August birthstone

Sardonyx: August birthstone

 

 

 

 

 

 

In 1912, Jewelers of America, an association with a definite interest in marketing gemstones, sought to standardize the list.  The official list of birthstones had garnet, amethyst, aquamarine, diamond, emerald, pearl, ruby, peridot, sapphire, opal, topaz (the orange-yellow-brown kind), and turquoise.  Some of the months had two birthstones, partly in deference to the traditional stones.  So March had aquamarine AND bloodstone.  August had peridot AND sardonyx.  But, let’s face it, if you were born in March, which gem would you rather have?  A transparent medium blue one or an opaque dark green one with red blemishes?  It didn’t take long to drop these traditional choices.

The 1912 list has had few changes in the last 100+ years.  In 1952, alexandrite was added as a birthstone for June and citrine was added as a birthstone for November.  December’s traditional birthstone of lapis lazuli was replaced with blue zircon.  In 2002, tanzanite, the blue-purple gemstone that had been discovered in 1967, was added to the list for December.  And, most recently, in 2016, spinel was added as a birthstone for August.

Why the additions?  Many people would say it’s a marketing move.  Birthstones aren’t really seen as bringing good luck or good health anymore.   They don’t have the significance they used to have.  They’re just fun.  So why not have more choices?  I’m really happy for all you August babies who no longer feel confined to the yellowish-green of peridot.  Spinel offers great variety! (See my blog on spinel–July 28, 2016).

So, what do we make of this idea of birthstones?  To me it sounds like a complicated game of Telephone.  Do you remember that game when someone whispers a phrase to someone else, and it goes around the circle?  The final uttering of the phrase bears no resemblance to the original.  That’s how I feel birthstones came to be.  From Aaron’s breastplate to the writings of Josephus to the Jewelers’ list, it’s a crazy, convoluted path. But this is where we are and what we have.  My suggestion?  Adopt your favorite gemstone, the one that has meaning to you,  and make it YOUR birthstone.

Book Review: Stoned by Aja Raden

Stoned

Stoned: Jewelry, Obsession, and how Desire Shapes the World by Aja Raden was published in 2015.  A friend bought me the book, and it may well be one the most thoughtful gifts I’ve ever received.  Gemology and history are two of my favorite subjects, and this book intertwines them into eight fascinating stories.  Each chapter is a stand-alone story, of places, events, and peoples as varied as the Spanish Armada and World War I or Marie Antoinette and Kokichi Mikimoto.

Aja Raden writes with a sense of humor and an irreverence for how humans can behave when they desire something.  Her stories are intriguing and revealing, and I love how she ties gems and jewelry into topics like economics and politics.  As the author states, jewelry isn’t just a set of objects, but symbols–“tangible stand-ins for intangible things.”

In a nutshell, the chapters discuss the following:

  1.  How glass beads bought Manhattan

  2.  History and rise in popularity of the diamond engagement ring

  3.  Emeralds and their significance to the Spanish Empire

  4. The necklace that “started” the French Revolution

  5. The pearl, Le Peregrina, that stirred the rivalry between two queens

  6. How Faberge’ eggs hurt Tsarist Russia and fueled Communism

  7. How Mikimoto’s cultured pearls saved the Japanese economy

  8. How wristwatches served in World War I

I enjoyed each chapter and feel that anyone who reads a jewelry blog would like this book.  If you read it, please share your thoughts through our website.

 

 

The New Birthstone- August’s Spinel

 

Natural Spinel

Natural Spinel

I have some very good news for all of you born in August.  Just recently, the American Gem Trade Association and Jewelers of America announced that SPINEL has been added to the birthstone list as an alternative to peridot.  Not everyone is a fan of peridot’s yellowish-green color, and the gem stone has a narrow range of hue.  Spinel, on the other hand, comes in almost every color of the rainbow!  The most prized color is red.  Pink and blue are two other popular hues.  So, because spinel is a relatively unknown gemstone and because changes to the birthstone list don’t happen often, it seemed important to write about it.

Peridot

Many people have never heard of spinel.  It was recognized as a separate mineral about 200 years ago, but, until then, red spinel was often mistaken for ruby.  Some famous gems, like the Black Prince’s Ruby, which is set in England’s Imperial State Crown, are actually red spinel.  Those who have heard of it often associate it with something “cheap” or “common.”  Synthetic (aka man-made) spinel has been used for years to make the stones for high school class rings because it’s inexpensive to produce in lots of different colors that mimic birthstones like emerald, ruby, and sapphire.  Synthetic spinel is also used as the top, bottom, or both of a “triplet” that substitutes for a natural gemstone.

Natural spinel is a beautiful mineral made of magnesium, aluminum, and oxygen.  It’s colorless unless a trace element such as chromium, iron, or cobalt makes its way into the recipe.  Chromium leads to a pink or red spinel.  Iron and cobalt lead to violet and blue spinels.  A combination of trace elements produces orange or purple spinels.  These colors need no enhancement, so spinel is rarely heat-treated or irradiated.  It’s a fairly hard gemstone, scoring 8 on the Mohs Scale, and it forms in the cubic crystal system.  These qualities mean that spinel is hard enough to take a good polish and easy enough to cut and facet.  And the gem is usually eye-clean when it comes to inclusions.

Spinel is traditionally associated with Asia–especially Myanmar, Vietnam, and Sri Lanka.  More recently deposits have been found in Tanzania and Madagascar.  Large crystals are quite rare, so the value goes up exponentially, not only for great color but also for size.  While not as expensive as fine ruby or pink sapphire, natural spinel is not an inexpensive gem.  Red spinel would cost approximately 30% of the cost of a similarly sized ruby.  And pink spinel would be about 85% of the cost of a same size pink sapphire.  It’s not easy to find spinel in a jewelry store.  Maybe that will change now that it’s a birthstone, but, up until now, it’s been more of a collector’s stone.

So, take heart all of you who longed for another birthstone! It’s spinel to the rescue!!  Ask your jewelry store for a peek at its spinel.  Here’s a peek at ours.

Quartz-So Common and yet so Special

Flawless Quartz Crystal Sphere at the Smithsonian Natural History Museum (106.75 lbs)

Flawless Quartz Crystal Sphere at the Smithsonian Natural History Museum (106.75 lbs)

This crystal sphere is the largest cut piece of  flawless quartz in the world, weighing in at 242,323 carats!  It symbolizes our fascination with something so beautiful and yet so common.  Quartz is found around the world, in large quantities, and is considered one of the most common minerals on Earth.  It’s found in sand, dirt, and dust.  Yet, when fashioned by gem cutters and put in a stunning piece of jewelry, it can be breathtaking.

Quartz is a complicated gemstone.  One of the reasons it’s tricky is because the term “quartz” is used for varieties of gems, as well as for a species of gem and as a group of gems.  So, for example, Rose Quartz is a variety of the species Quartz.  So is Citrine, Amethyst, and Tiger’s Eye!  All these varieties, and others that are couched under the species of Chalcedony, such as Agate and Jasper, are considered to be members of the group, Quartz.  Very confusing!!

Perhaps it’s best to start with the fact that mineralogists and geologists see any mineral with the chemical makeup of silicon dioxide, SiO2, as Quartz.  Regardless of whether the crystals making up that stone are large, small, or microscopic, it’s all Quartz.  Gemologists, on the other hand, separate the gems into those whose crystals are larger and those too small to see without a high-powered microscope.  Those with larger crystals are called Quartz and those with microcrystalline structures are labeled Chalcedony.

Under these two species are many varieties that are used in jewelry.  Probably the most commonly known variety of the quartz species is Amethyst.  That regal purple has been admired for centuries.  The purple color comes from natural irradiation acting upon a trace element of iron.  The saturated, medium to deep reddish purple is the most prized color, but amethyst ranges from a light, pinkish purple to that deep purple hue.  Amethyst is not rare, but the prized color is more rare because usually only the tips of the amethyst crystals have that depth of color.

Other varieties of the Quartz species include Citrine, the orange-yellow gemstone that’s November’s birthstone, and Rock Crystal, which is colorless because it has no trace elements.  There’s also Rose Quartz, Smoky Quartz, Prasiolite (aka Green Amethyst), and Ametrine (a bi-colored gem combining the purple of Amethyst and the yellow of Citrine).

Members the Chalcedony species have been used in jewelry even longer than Amethyst!  Agates, which exhibit wavy bands of color, were used in amulets and talismans over 3000 years ago.  They were also used to make cameos.  Carvers would reveal a differently colored band by carving down around the subject of the piece.  Today you’ll see agate slice pendants that are sometimes dyed to accentuate the banding.

Probably the most valuable member of the Chalcedony species is Chrysoprase.  This translucent gemstone is beloved for its natural apple-green color.  It owes its color to the presence of  nickel.  A big discovery of Chrysoprase was made in 1965 in Australia.  Because its color can resemble fine jadeite, it’s sometimes called “Australian Jade.”

Other varieties of the Chalcedony species include Black Onyx (dyed black chalcedony), Carnelian, Jasper, and Fire Agate.  Most chalcedony is translucent to opaque, so it’s rarely faceted.  Most often it’s fashioned into beads, slices or cabochons.  But, just like all Quartz, it registers a 7 on the Mohs Hardness Scale, making it a good choice for rings and bracelets as well as earrings and pendants.

There’s so much that can be said about this beautiful mineral that surrounds us everyday.  But I want to end with the sentiment– “How wonderful when something so common can also be so special!”

The Latest Trend: the Two-Stone Ring

Maybe you’ve seen the ads on TV.  A laughing couple in a car, sharing a private moment as they drive a country road.  They are in love.  But they’re also best friends.  And that’s the story of the two-stone engagement ring.  It represents the dual nature of their relationship.

two-stone ring

The two-stone ring is the latest in a fairly long line of styles promoted by De Beers, the diamond company that, for most of the last century, was the biggest supplier of uncut diamonds.  Their ability to create demand for diamonds started with the famous phrase from the 1940s–A Diamond is Forever.  And it worked so well that Ad Age, a magazine that analyzes and reports on the marketing world, named it the number one slogan of the 20th century.

A decade ago, it was all about the three-stone engagement ring, or, as it was sometimes called, the trinity ring.  The three stones signify your relationship’s past, present, and future.  Or the trio can be seen as signifying friendship, love, and fidelity.   The most common version of this ring had smaller stones on the left and right with a larger stone in the middle.

Also around ten years ago, the journey necklace was advertised widely as a sentimental way to think about your journey together with the person you love.  Their were several styles, for example the ladder, circle, heart, or S, but most had five or seven diamonds.

journey necklace1journey necklace2

 

 

 

 

 

Other pieces De Beers promoted were the diamond tennis bracelet (1988), the bezel-set diamond solitaire necklace (1998), and the right-hand ring (2003).  I laughed when I saw the date on the bezel-set necklace.  My husband bought me my necklace in 1999.  It’s funny because I’ve never thought of advertising as being influential on my husband or myself.  We don’t watch much TV and we hardly ever pay attention to commercials, except for the Superbowl ads.  But good advertising does work, and the company that advertises for De Beers is very, very good at it.

And their goal is obvious.  They want you to buy more diamonds and especially smaller diamonds.  Why smaller?  Because there are many, many more small diamonds than large.  That’s also the reason why buying a carat’s worth of small diamonds is much less expensive than buying a single, one carat stone.  As a quick test, I looked at one diamond vendor’s pricing on one carat, one-half carat, and one-third carat stones.  The pricing follows a more exponential pattern.  Keeping the other variables of cut, color, and clarity stable, a 1/3-carat stone was about $1000, a 1/2- carat was $3000, and a 1-carat was around $9000.  A three-stone or two-stone ring, by carat weight, can be quite cost effective.

The point of my blog is this:  Buy a style of ring you love rather than the style that is being promoted at the moment.  Don’t get swayed by the sentimentality of the story.  Your ring should represent what you want it to represent–not some story made up by someone in advertising.

 

 

Colorful Stories of Three Colored Gemstones

The romance and history of colored gemstones has always fascinated me.  I guess I’m just a sucker for a good story.  Here are three I thought you might like.

TANZANITE:  It’s said that we are all members of the “Tanzanite generation.”  Discovered in 1967 by a Masai tribesman in Northern Tanzania, Tanzanite is mined in only one, 4 square kilometer, location.  And the mines are getting deeper and harder to mine profitably.   We will be the ones who can buy a new Tanzanite.  Future generations will only see the stone in heirloom pieces.  It’s estimated that Tanzanite One, the largest Tanzanite mining company, has less than 30 years of production left.

The gemstone was named by Henry Platt, great-grandson of the famous Louis C. Tiffany.  Tiffany and Co. realized the importance of the gemstone and quickly made themselves the main distributor.  Their marketing efforts made tanzanite one of the most popular gemstones by the 1990s.  The beautiful gem hit the big screen with a “splash” as the Heart of the Ocean in the movie, Titanic.

MORGANITE: This pink to orange/pink variety of beryl was originally discovered in Pala, California in the early 1900s.  It was named for J.P. Morgan, a great financier and collector of minerals.  Tiffany’s gem buyer and gemologist, George Kunz, was the man who named the gem, buying up all he could find for his wealthy client.  Incidentally, another pink gemstone, discovered at about the same time, was named Kunzite in honor of George Kunz.  So, he got his own gemstone, too!

Morganite is the same species of mineral as Emerald and Aquamarine.  Like Aquamarine, it is usually an eye-clean stone that can be cut in larger sizes.  It’s a good thing, too, because a larger stone usually shows a more saturated color.  Pale Morganite often needs that advantage.   It’s generally heat-treated to improve its pink color and minimize its yellowish tint.  The treatment is stable, so no fading occurs. morganite2

ALEXANDRITE: First discovered in Russia’s Ural Mountains in the early 1830s,  Alexandrite is the quintessential color-change gemstone.  It was found by miners who thought they’d found emeralds, until nighttime came and they were sitting around the campfire.  Alexandrite’s trace elements of iron, titanium, and chromium make it greenish in sunlight and reddish in incandescent or fire light.  Boy, were those miners surprised when, the next morning, their red gemstones had turned back to green!

Legend says that the gem was found on the 16th birthday of young Alexander II, future Czar of Russia.  The stone became the National Gem of Czarist Russia.  It was the perfect fit with the red and green color scheme of imperial Russia’s military.  Every Russian had to have an Alexandrite.  Unfortunately, for all of us, the Russian supply was depleted.  Fortunately, other deposits have been found in Sri Lanka, East Africa, and Brazil.

Natural Alexandrites are very expensive, especially in larger sizes.  Even the synthetic version is expensive, because it’s difficult to manufacture.  But, if you’re lucky enough to own an Alexandrite, you have an “Emerald by day, and a Ruby by night.”

The Story of Campbellite

campbellite

I’ve lived most of my life in Michigan and my maiden name is Campbell.  Most people don’t know that because I’ve been married so long!  But I always thought Campbell was a good name, so I was both happy and surprised to learn that there is a gemstone named after. . .no, not me, nor my kinfolk, but after the Campbell shaft of the well known Bisbee Mine in Southern Arizona.

So, what’s the story of Campbellite?  As explained by one of the stone cutters at Arizona Lapidary, Campbellite is an uncertain  mixture of minerals like cuprite, azurite, malachite, calcite,chrysocolla, pyrite, quartz, and copper.  Its color and look varies because there’s no set amount of these minerals.  It was first discovered by miners looking for copper.  The bosses weren’t interested in this unusual rock, and told the miners to discard it.  But the miners had a different plan.  They saw its beauty.  So, yes, they dumped the Campbellite in the trashcan.  But they separated it carefully from the real trash.  And when no one was looking, they loaded the discarded gem into the back ends of pickups.  Campbellite has been showing up in the market, piece by piece.  There’s not a lot of it–I’m sure plenty WAS dumped.  The mine closed in 1975, and there is no other known source of Campbellite.  But I bought one piece of it, cut into a smooth cabochon, and plan to make a bolo tie for my dad.

I learned a little bit about the mine shaft itself.  It was first developed in 1927, originally as a way to get oxygen to other parts of the Bisbee Mine.  But soon it was one of the best producers of copper ore, with yields of 8-10% copper.

Finally, who is the Campbell shaft named after?  A little research revealed an amazing coincidence.  The shaft was named after Gordon R. Campbell, who actually lived and went to school in Michigan!  He graduated from U of M in 1893 and was a mining executive and lawyer up in the Keweenaw Peninsula.  The Keweenaw Peninsula, jutting from the Upper Peninsula of Michigan, is one of the best known sources of copper world-wide.   Towns like Calumet, Houghton, and Copper Harbor were booming back in the mid-1800s because of copper.  Anyway, Gordon Campbell helped form the Calumet and Arizona Mining Company in 1901, serving as the company’s President from 1921-1931.   It was this company that operated the Bisbee Mine.  So Campbellite WAS named for a Campbell living in Michigan.  Who knows?  Maybe he’s a long, lost cousin?

A Group to Know–the American Gem Society

American Gem Society

If you’ve bought a diamond recently, it probably came with a diamond report.  And that report might very well have come from the American Gem Society Laboratories (A.G.S.L.).  The story of the American Gem Society is an interesting one that started back in 1934.   Back then and still today, the A.G.S. is an organization dedicated to the maintenance of high ethical standards in the jewelry industry.  Its primary purposes are 1) to encourage professional education within the jewelry industry and 2) build consumer confidence and trust in the knowledge, integrity, and competence of professionals in the jewelry industry.

Robert Shipley is the man responsible for starting A.G.S.  He came from a retail jewelry background here in the U.S., but, after spending some time in Paris learning more about gemology, he felt that the industry lacked the education it needed.  He started a correspondence school in 1931 called the Gemological Institute of America (G.I.A.) Three years later he established the American Gem Society, a sort of alumni association of G.I.A.  The society started out small, and it was housed in the same building as G.I.A.  Mr. Shipley was the President of G.I.A. and the Executive Director of A.G.S.

Al Woodhill took over as Executive Director of A.G.S. in 1946, and in 1948 the organization moved into its own headquarters.  In 1955, A.G.S. established a Diamond Standards Committee which published the first A.G.S. Diamond Grading Standards Manual in 1966.   Diamonds are evaluated using the 4Cs–cut, color, clarity, and carat weight.  Carat weight is measured, but cut, color, and clarity are graded using a 0 – 10 point scale.   Triple zero would be the grade given to the Ideally cut, Colorless, and Flawless diamond.

The American Gem Society , LLC opened in 1996 and became a leader in the grading of diamonds.  Its Diamond Quality Document presents a complete analysis and documentation of the 4Cs.  It provides both the professional and the customer with the details needed to fully understand what is being purchased.

Today’s customers can feel confident about their purchases if they are buying from an A.G.S. member store.  Standards and regulations protect the consumer in a way that customers one hundred years ago could never have expected.  Consumer confidence benefits everyone–customers, retailers, and suppliers.  We owe our appreciation to Robert Shipley and the American Gem Society.
