This Gem Cutter Won Spectrum’s ‘Best of Show’ Award Again
David Nassi of 100% Natural Ltd. took the top honor for the second year in a row with a big pair of spessartite garnets.

AGTA held the jewelry design and gemstone cutting competition on Oct. 24 and 25 in Dallas rather than New York City, as it usually does, due to travel restrictions amid the continued pandemic.
The judges were: Michael Johnson, Eiseman Jewels; Monica Kitt, Arkenstone Ltd.; Clare Adams Kittle, Clare Adams Kittle Company; Chris Pampillonia, Pampillonia Designs; and Ray Zajicek, Equatorian Imports.
This year’s contest had 20 percent more entries, as well as many first-time entrants, AGTA said, and included two new categories.
AGTA added North American Mined Gemstones to Cutting Edge, the division of the contest dedicated to lapidary arts. It said the new category was the largest in that division this year.
It also added Best of Single Entries, chosen from applicants who submitted only one piece in the competition, and gave the award in both Spectrum and Cutting Edge.
This year, the top overall honor, Best of Show, went to a pair of pear-shaped spessartite garnets weighing a total of 90.48 carats cut by David Nassi of 100% Natural Ltd.
This is the second year in a row Nassi has nabbed top the awards’ top honor, after his 30.19-carat untreated cushion-cut red spinel wowed the judges last year.
His victory also extends the winning streak for faceted loose stones at Spectrum, which have won Best in Show four out of the last five years.
