Demantoid Garnet Suite Takes Top Spectrum Honors
This is the second time in as many years that a Cutting Edge entry took home Best of Show honors in the AGTA’s annual design contest.
This suite of round brilliant demantoid garnets weighing 24.67 total carats won Best of Show in this year’s AGTA Spectrum Awards.
Dallas--For the second time in as many years, a Cutting Edge entry took home the Best of Show honors in the American Gem Trade Association’s Spectrum Awards.
A suite of round brilliant Russian demantoid garnets weighing a total of 24.67 carats cut by Ruben Bindra of B&B Fine Gems was recognized with the design contest’s highest honor.
Last year, a suite of carved Paraiba tourmaline won Best of Show.
There has only been one other time a Cutting Edge entry has won the competition’s top honor--in 2004, Best of Show went to a sunstone, moldavite and diamond “Celestial City” carving.
Judging for this year’s Spectrum Awards took place Saturday and Sunday in New York. It was the first time that the competition was held in the summer rather than the fall.
This year’s judges were: Gail Brett-Levine of National Association of Jewelry Appraisers, Diane Garmendia of 33 Jewels at El Paseo, Jay Mednikow of J.H. Mednikow & Co., Inc. Victor Velyan of Victor-Christy Studios and Lew Wackler of Lew Wackler Gem Co.
The winners will receive their awards during the 2017 AGTA GemFair in Tucson, scheduled for Jan. 31 to Feb. 5 at the Tucson Convention Center. Winning entries will be displayed during the show and the award winners will be recognized during the Spectrum Awards Gala on Feb 4.
