The fabulous platinum and gemstone creations shown here recently earned 16 outstanding designers the coveted Platinum Honors, a special category in the annual AGTA Spectrum Awards competition. Platinum Honors, now in its fifth year, is an exciting opportunity for designers to demonstrate their creativity and design sense through the combined medium of precious platinum and colored gemstones.
Of the more than 300 entries to the Spectrum Awards competition, 86 qualified for Platinum Honors considerations. “Once again, the competing designers have shown an astonishing array of creativity and talent in the year’s Platinum Honors Competition,” said PGI President Laurie Hudson. “The innovative and playful designs are as diverse as platinum itself.”
Entries were judged on their beauty and originality, as well as the effective and innovative use of platinum. Here are the winners: . . . (1) Sessin Durgham, Jack Seibert Goldsmith Jeweler,
