DALLAS. July 26, 2023 – The American Gem Trade Association (AGTA) is pleased to reveal the judges for the 2023 AGTA Spectrum & Cutting Edge Awards™. Five judges were selected for the panel, which comprises experts from different disciplines within the jewelry industry. Judges are tasked with assessing hundreds of entries based on the criteria of beauty and wearability, innovative design, effective use of materials, quality of gemstones, quality of workmanship, consumer appeal, and potential to generate positive publicity for natural colored gemstones and cultured Pearls. Each piece is examined by hand with an eye for craftsmanship and quality of the materials used.

“AGTA is thrilled to have such a prestigious group of judges choose competition winners this year,” said John W. Ford Sr., CEO of AGTA. “We look forward to seeing all the entries and seeing how the choices are made. Receiving AGTA Spectrum & Cutting Edge Awards™ is lifechanging for many—something I know firsthand from days as an Opal dealer and winner!”

Judging will take place in Dallas in late October. Judges for this year include:

Allan Koo

Koo is the Owner of A. Koo & Co. and started his lapidary career in Hong Kong more than four decades ago. He immigrated to the U.S. in 1979 to advance his skills, learning from a master gem cutter name Frank Lani. Now based in New York City, Koo provides cutting, polishing, and repair services on precious gemstones to an international client base. Koo’s work is renowned for a signature style of freehand cuts and stands as a paragon of excellence in the lapidary world.

Brent Malgarin

Malgarin owns Elegant Gems, Ltd., a boutique jewelry store in Edmonds, Washington, with his wife. Malgarin’s passion for gemstones started in childhood, collecting and tumbling rocks found near a family cabin. He secured his graduate gemologist degree at GIA, afterwards returning to Seattle to work in retail and in wholesale. In the late 1980s, he made his way to the Tucson Gem and Mineral Show and from there added faceting skills to his résumé followed by several Spectrum and Cutting Edge^TM Awards.
