Every year, since 1984, the AGTA (American Gem Trade Association) hosts competitions to bring out the best jewelry designers and stone cutters in the industry. Qualified judges are selected to narrow the many entries down to first, second, third, and, sometimes, fourth place finishers. The Spectrum Awards and the Cutting Edge Awards are considered the world’s preeminent competitions for design with colored gemstones and cultured pearls.
Here at Dearborn Jewelers, we design a lot of jewelry, both to sell in the store and for individual customers. We purchase colored gemstones to put into our designs, and the cutting of those gemstones is of ultimate importance. If a stone isn’t cut properly, it will not reflect light well and could look ‘sleepy’. A great stone cutter can add tremendous value to the gemstones he/she cuts.
This year saw an increase in the number of loose gemstones that were entered in the Cutting Edge competition. According to Douglas Hucker, CEO of the American Gem Trade Association, “diversity was evidenced in the absolute cornucopia of color and variety.” The entries were placed into one of four groups– 1) Classic Gemstones; 2) All Other Faceted; 3) Innovative Faceting; and 4) Carving. Five judges, well-known in the jewelry industry, were selected to select the winners. The competition was held in New York City on August 4-5, 2018. Our congratulations goes to the winners! And here they are:

Most of us think of Michelangelo, Picasso, or Rodin when someone mentions sculptors. But here are three more names of skilled artists who sculpt and polish gem stones. Tom Munsteiner, Steve Walters, and John Dyer have all won multiple awards for their work. Here are some examples:
Tom Munsteiner is a fourth generation gem stone carver from Germany. His father, Bernd Munsteiner, is famous for the development of the fantasy cut, and he even has some of his work in the Smithsonian! Tom knew early on that he wanted to carve gems. At age 16 he began training with his dad. One thing I found very interesting is that his dad first taught him how to classically cut gems before attempting any fantasy cuts. By the time he was 22, he had been trained as a Gemologist and was beginning to win awards for his gemstone creations. His work is distinguished from his father’s for its softer, less angular designs.
Steve Walters grew up in California. He taught himself how to carve gemstones by reading books and practicing. For a short period, he produced gemstone sculptures for his parents’ company. In the mid-1980s he started to carve gems for jewelry. His work is very recognizable as many of the pieces are composites. He might put gems like onyx, citrine, and hematite together, backed with mother of pearl. He’s won several A.G.T.A. (American Gem Trade Association) Cutting Edge Awards, and his booth at the Tucson Gem Show is always one of the most popular.
John Dyer grew up in Brazil, the son of missionaries from the United States. When his parents saw his interest in gems, they bought him books and helped him obtain his first rough gem stone material. John tells the story of taking his rough to a cutter who overcharged him and did a terrible job. That’s when he decided to cut his own gems. With lots of practice and a few “disasters”, he’s become one of the most recognized gem stone cutters and has won over 50 cutting awards.
At Dearborn Jewelers of Plymouth, we’ve been fortunate to set gem stones cut by all three of these artists. It’s so gratifying to see these gems being worn and appreciated. Here are some of our designs. If you’re inspired to have your own creation by one of these well-known artists, come and talk to us. We’d love to help.

The history of lab-created or synthetic gemstones is much longer than you might think. Scientists began making synthetic ruby back in the late 1800’s. Initially, rubies were made for industrial rather than decorative purposes. Ruby is harder than steel, so it can hold up to moving metal parts. It actually helps reduce friction in devices like watches or compasses, allowing the metal pieces to move with a consistent pattern.
In the early 1900’s, a young boy named Carroll Chatham tried to grow diamonds in his garage. He was fascinated with the work of Henri Moissan, a French chemist who also tried to grow diamonds but ended up with Moissanite. Making diamonds requires more heat and pressure than Chatham could produce at the time, so he re-directed his focus to emeralds. Even then, the work wasn’t easy. In fact, his first emerald crystals were accidentally formed. By this time Chatham was in college, and it took him three years to figure out how to replicate the “accident.”

By 1938, Chatham had perfected the process of growing emeralds for jewelry, and he moved on to creating other valued gems like sapphire, ruby, opal, spinel, and alexandrite. Chatham began selling his lab-created gems under the Chatham label. The company is now 80 years old and is one of the leaders in the making of lab-created colored gem stones. Carroll never gave up on his dream of growing diamonds and, in the late 1980’s, the company was successful. Unfortunately, Carroll didn’t live to see this dream come true.
In 2018 there are many, many companies that produce diamonds–companies like Brilliant Earth, Clean Origin, and EcoStar. Years of refining the High Pressure, High Temperature technique has led to better quality diamonds. While diamonds have many industrial uses, today’s lab-created diamonds are beautiful and can also be used in jewelry. Anyone purchasing an engagement ring today has a decision to make that his/her parents and grandparents didn’t have to make–Should the center stone be natural or lab-grown?

There are pros and cons to purchasing a synthetic diamond or colored gemstone. Some of the advantages are 1) synthetics are less expensive than their natural counterparts; 2) growing synthetics is kinder to the environment than mining for natural stones; and 3) gem cutters can sacrifice more synthetic material to create the perfectly cut gem because, well, you can always grow more! Partly because of these advantages, we’ve seen more customers move towards this option.
One big disadvantage of a synthetic stone is that it’s, well, synthetic. Fine jewelry symbolizes pure and natural feelings of love, gratitude, or friendship. How will it feel to wear or give jewelry that has a lab-created stone? Another disadvantage is that synthetic stones will only go down in value. They are a manufactured item and, as the technology improves in the making of them, the cost to produce will decrease. Fine natural gems are rare, and that rarity will keep values high.
It’s a decision every consumer has to make for him/herself. What’s imperative is that consumers are presented with clear options, and that they know what they are buying. Gemstones are not obviously natural or synthetic, so customers must rely on reputable jewelers to distinguish between the two. For an important jewelry purchase, go to an A.G.S. (American Gem Society) member store. There you will find associates dedicated to the highest integrity in the jewelry industry. Ask questions and do comparison shopping. And feel lucky to live in a time when there are so many gem stone options.
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!
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!”

This blog is the first of a series on gemstone treatments. The truth is, all gemstones have been modified by man. We’d like to think that a gemstone’s beauty is completely natural, but the reality is man plays a part. Cutting and polishing bring out the sparkle and color. Shaping and setting is all done by man. So a gemstone’s beauty can be attributed to both man and nature. Each consumer must decide what level of man’s contribution is acceptable. Everyone sees that man must be involved to some degree, but opinions vary on enhancements such as irradiation, dyeing, or fracture-filling. Is there a point where man’s contribution to a gemstone’s beauty goes over the fine line, when the stone just doesn’t seem natural anymore?
Another fine line is the one jewelers walk everyday when conversing with customers about gemstones. There are laws and guidelines, set by the government and the AGTA (American Gem Trade Association), for disclosure of gemstone treatments. But jewelers adhering to those guidelines also have to make sales in order to stay in business. Some customers are truly interested in learning about how gemstones arrive at their beautiful state. But many would be bored by a lesson in gemstone treatments and might walk away from a sales representative who insisted on giving all the details. Certainly anyone who sells jewelry should honestly answer customer questions about gemstone enhancements or treatments. We want our customers to understand as much as they’d like to understand about gemstone treatments. We want them to understand that, if treatments didn’t exist, most of us would be unable to afford pretty gemstones.
So that’s what the series will be about. It will give you an overview of some of the main treatments on some of the most common gemstones in the market. The series will also discuss some gemstones that are not treated–ONLY cut, polished, and set. If you find this fascinating, I will include some sources for learning more. And remember, if you want to know more about the gemstone you’re buying, just ask.
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?

Perhaps you’ve seen the phrase, “Lazare. . .the World’s Most Beautiful Diamond.” Your mind might question the assertion. After all, aren’t all diamonds beautiful? How can a company make this claim?
The answer lies in the cut. In 1919, the cousin of founder, Lazare Kaplan, developed a mathematical thesis for cutting diamonds to precise angles and proportions to gain the optimum reflection and refraction of light. When a diamond is ideally cut, light rays from all sides are bent towards the center of the diamond and are reflected back through the top. If not ideally cut, light will “leak out” through the sides or bottom of the diamond. The beauty of a colorless diamond is all about its brilliance, scintillation, and fire. The Lazare Ideal cut maximizes all three.
A beautiful diamond is also tied to a company that does good work in its community. Lazare Kaplan International, Inc. supports a number of important causes in Namibia, where most of its diamonds are mined. LKI also supports policies that
protect fundamental human rights and the dignity of the individual
prohibit the trade in conflict diamonds (zero tolerance policy for conflict diamonds and strictly adheres to all protocols of the Kimberly Process)
prevent money laundering and combat the financing of terrorism
ensure business is conducted in an environmentally responsible manner
Finally, a beautiful diamond is one that can be yours forever. Every Lazare diamond of 0.18 carats and higher has the Lazare logo and an individual identification number, laser inscribed on the diamond’s girdle. This logo is your proof of authenticity as an ideal cut Lazare diamond, and the identification number is your proof of ownership.
Lazare Kaplan International, Inc. has been in business since 1903. It plans to be around for a long time to come. When it’s your turn to look for the world’s most beautiful diamond, be sure to remember Lazare.
If you love gemstones, ask your jeweler if he/she hosts roundtable events. These are usually evening events that last 2 – 3 hours, taking place after your jewelry store closes. Food and drink are often served, and you are introduced to a gemstone expert. This expert shares knowledge and stories about gemstones and the gemstone industry. Sitting at a, usually rectangular, table, guests are given the chance to see, touch, and dib on approximately 100 different gemstones. Dibbing simply means that you would like another look at that gemstone after it has gone around the table. These gemstones are for sale, but there is never an obligation to buy. The goal is to have fun learning about and playing with gemstones.
More people want to be involved in the making of their jewelry. Mountings can mask flaws of gemstones, so it’s to the buyer’s advantage to see gemstones un-mounted. And mountings can be unique if you work with a custom designer. On-staff designers are generally at the roundtable event and they can help you with ideas for any gemstone you select for purchase. The whole process of 1) picking out the gemstone; 2) deciding on a design; and 3) having the piece made by your local jeweler is a memorable one.
Dearborn Jewelers recently hosted a roundtable event with gemstone dealer, Judith Whitehead. Our next event will be in September. If you are interested in attending, give us a call and we can put you on the list. It promises to be a great time.
