by JPie » Mar 5, 2019 Here she is! I bought an Afghan mint tourmaline from Jeff White a few weeks ago, and David Klass made the setting in platinum. He picked the diamonds on the sides and did an amazing job! Details: Platinum, 7.1 grams, set with .81cts of G color, VS clarity pear shape and marquise diamonds, size 6.5. The untreated tourmaline is 2.99 ct and measures 9.39 x 6.74.
