AGTA Reveals Spectrum, Cutting Edge Award Winners for 2024
This year’s AGTA Spectrum & Cutting Edge Awards included a new category for engagement rings and a new award highlighting female designers.
A platinum and 18-karat yellow gold brooch titled “Sophia D En Tremblant Butterfly” (left) from Joseph Dardashti of Joseph Dardashti Ltd. and Sophia D. featuring emeralds, rubies, sapphires, and diamonds won Best of Show honors in the Spectrum division, while a 33-carat Montana sapphire called “The Montana Sun Sapphire” from John Dyer of John Dyer Gems took home Best of Show honors in the Cutting Edge division.
Dallas—The American Gem Trade Association announced the winners of the 2024 AGTA Spectrum & Cutting Edge Awards this week.
Judging for the contest, now in its 40th year, took place Oct. 31 and Nov. 1 at the Omni Frisco Hotel at the Star in Dallas.
There were more than 375 entries, which AGTA CEO John W. Ford Sr. said was similar to the previous year and included a “substantial number” of first-time entrants.
Category distribution also was comparable to 2023.
“Every year the quality of our entries continues to get better and better,” said Ford.
The Evening Wear category had the most entries at 75, while Men’s Wear had 27 entries, a slight increase from last year.
A new category was introduced this year for engagement rings.
It had 21 entries, which Ford described as “an explosion of vibrant color” that “far outweighed my expectations.”
“We are thrilled to see artists’ colorful takes in an area that has traditionally been reserved for diamonds,” he said of the new category.
A new award also was introduced this year.
The Alfie Norville Women in Excellence Awards, sponsored by Allan Norville and the Norville family, were created to highlight female designers. The designation was given to one female entrant in each of the six Spectrum categories.
The 2024 AGTA Spectrum & Cutting Edge Awards judges included Jean Francois Bibet, Cartier; Sherry Bender, The Goldsmith Ltd., Chicago; Susan Jacques, Gemological Institute of America; and Suzy Landa, Suzy Landa Fine Jewelry.
An additional judge, Peggy Grosz, formerly of Assael, withdrew due to a conflict.
“We have returned to Texas for a fourth time, and this may be our best year yet,” said Kimberly Collins, owner of Kimberly Collins Colored Gems and president of the AGTA board of directors.
“The caliber of the entries continues to increase annually, and the expertise of the judges wows us. I think everyone loved seeing the submissions in the new engagement ring category, as colored gems in bridal are a growing segment of the market.”
Spectrum award entries are judged on overall beauty and wearability, innovative design, effective use of materials, quality of gemstones, quality of workmanship, broad‐based consumer appeal and potential to generate positive publicity for natural colored gemstones, natural pearls and cultured pearls.
Cutting Edge awards honor excellence and creativity in the lapidary arts, including natural colored gemstones and cultured pearls, carvings, and other gem materials.
Many of the winning pieces will be on display during AGTA GemFair Tucson, slated for Feb. 3–9 in Tucson, Arizona.
Winners will be recognized at the AGTA Spectrum Gala, scheduled to take place Feb. 8 in the recent addition to the Tucson Convention Center.
Here they are.
