Meet the 2019 AGTA Spectrum Awards™ Judges

Paula Crevoshay, Mellika Company, Inc. / Crevoshay

Some great artists show a flash of genius and are gone, some show us a new vision and spend the rest of their careers repeating themselves and a few, the very greatest, continue to explore and reinvent themselves year after year taking their work and their audience to ever greater heights, enriching the broader culture in the process.  Paula Crevoshay is widely recognized to be among the very few in the latter group.

From the very beginning Crevoshay has applied Fine Art Principles to jewelry design.   In addition to Fine Art, Crevoshay studied Anthropology, especially symbolism, and you will note in her very modern expression of artistic archetypes echoes of cultures past.

Today Crevoshay enjoys the patronage of art connoisseurs and avid jewelry collectors the world over.  Her work has been exhibited in museums in the United States, France and India and is on display at the Gemological Institute of America, Carnegie Museum of Natural History and in the National Gem Collection at the Smithsonian where it continues to surprise and delight new people every year. 

John L. Carter, Jack Lewis Jewelers

John Carter began his jewelry career at Jack Lewis Jewelers, as a junior in high school where he stayed all through his college years, as well. Upon his graduation from Illinois State University with a bachelor’s degree in Marketing, he departed his hometown and Jack Lewis, as a traveling sales representative with Maurice Lacroix Swiss watches. Carter returned to Jack Lewis in 2002 as a partner and a ten-year plan to purchase the store. He accomplished this task in 8 and a half years and officially took the reins in 2011.

Through the years, Carter has been eager to innovate especially as it applies to shaping the 90- year-old store that he grew up in and loves. The store’s social media has been the vehicle that has gained the attention of Central Illinois customers, as well as respected jewelry industry leaders. He continues to set Jack Lewis apart through the store’s employees, creative messages, and unique product assortment.

Today, Carter is very active within the industry and his community. He is particularly proud of his role on the Board of Directors for The American Gem Society, where he currently serves as President.

Naomi Sarna, Naomi Sarna Designs

Naomi’s earliest memory is working with her hands; this has been the focus of her entire life, studying the beautiful line and making it come true with the work of her hands. Her interest in nature and what comes out of the Earth was sparked at a young age. She became familiar with minerals and gems while exploring mines in Montana with her grandfather who sold miners’ equipment.

Naomi has made a point of connecting with her work from the source. She has traveled the world searching for gems, some of her most wonderful memories include going to Tanzania to the tanzanite mines and developing a relationship with the Maasai.

Naomi is the winner many prestigious awards, both nationally and internationally. Amongst these are twenty-three of Spectrum Awards in both Gem Carving and Jewelry, including “Best Use of Color”, three consecutive “Best Use of Pearls”, two “WJA Gem DIVA™” and the first awarded “AGTA Buyer’s Choice Award”. Naomi is also the recipient of a Bronze and a Silver Metal from the Zi Gang Bei Jade Carving Association in Suzhou, China.

Her work is represented in the Permanent Collection of the Smithsonian Institution and is worn by high-ranking American government officials, as well as royalty. Her work has also been displayed in books and museums around the country including the Carnegie Museums in Pittsburgh and Headley-Whittney Museum in Lexington, Kentucky.

Today, Naomi is based in New York City. Her jewelry incorporates unusual natural pearls, colored pearls, and her own gem carvings. Her work is known for its meticulous fit and finish. Her carvings are of a unique design indicative of her interest in the way things flow and fold, inspired by water and fabric as she continues her study of the beautiful line.

She is deeply grateful to the AGTA for being the foundation for the development of her career.

Myriam Galli, Gemveto

Mimi Galli was born into jewelry and has been involved in the industry for the past 31 years.

Her mother and stepfather, Jean and Irene Vitau, founded Gemveto Jewelry Co, Inc., 55 years ago and Mimi has been a part of the company for the last 31 years, involved in all aspects of the business.

Started out in the administrative end and working closely with the stone buyer to learn about gemstone and diamonds, Mimi now does all product development, sales and marketing, and color gemstone purchases. Her parents instilled in her the knowledge and deep appreciation for fine, high quality jewelry and the importance of very fine craftsmanship and materials. As a young child she would come to the office and “play” with stones or sit and watch different aspects of manufacturing in the Gemveto atelier.

Her father, Maurice Galli, was a renowned jewelry designer, who worked for the big New York houses,

Tiffany, Van Cleef & Arpel, David Webb and Harry Winston. He also taught jewelry design at F.I.T. and published three jewelry design books. As a little girl, Mimi would visit her father at work and he would sit her down with paper and colored pencils or paints so she could designs her own jewelry.  Mimi inherited from her father a keen eye for color and design. Her passion is finding unusual gemstones and creating design around interesting gemstone color combinations and working closely with Gemveto’s talented model makers and craftsman to create unique pieces.

Mimi proudly served on the board of the Women’s Jewelry Association in the early days, where she had the privilege of working with amazing, accomplished industry women.

Brett Kosnar, Kosnar Gem Co.

Brett Kosnar has been in the gem industry for his entire life.  Starting with a family-owned business that specialized in world class mineral specimens, he became enchanted with the world of gems from a young age.  The family was in the heart of the mineral industry and had a mineral named for them, Kosnarite.  He then worked in the mining industry, bringing rock out of the Earth, giving him a greater understanding and appreciation of this world.  That knowledge led him to becoming a self-taught faceter and gemstone artist in his teen years, discovering how to shape what the world had to offer.  With his study of minerals, Brett was interested in working with the rare and unique stones that weren’t often used for jewelry.  These unique gems were not well known to jewelers and he found himself in need of a jewelry artist with the drive and knowledge to work with these stone.  Subsequently, he knew he would be the one to create these rare pieces, and began an apprenticeship under a master goldsmith.  Those skills would build the foundation for a passionate lifelong career.

Every year, Brett’s passion for the vast world of gems has expanded, driving him to hone his skills at both the stone and metal arts.  He has developed new techniques for the faceting of soft stones, which has set a new industry standard.  His particular skill with Fluorite and Rhodochrosite has set him apart for the rare gem stone industry.  He recently has added an AGTA Cutting Edge Award™ to his accomplishments.  Most recently, he had the privilege to take his first lapidary class under Dalan Hargrave and expand his skills further than they had ever been. 

Brett now owns and operates his own business with his wife, and fellow faceter.  Together, they labor to create spectacular gems every day and push the boundaries of gemstone artistry.  He also gives talks on the world of gemstones and what beauty lies beneath the Earth.  Brett’s devotion to the discovery and creation of gemstones, and the gemstone industry as a whole, is hardly to be rivaled.
