River Pebbles Ring with Trillion-Cut Green Tourmaline and Diamond

River Pebbles rings are made with 14k white and 18k yellow gold, and incorporate a variety of gems. Rona happens to love green tourmaline; shown here is a breath-taking 6mm trillion-cut green tourmaline from Brazil with an "E" color (very, very white) full-cut 3mm round diamond. You may also send us your gems to use in this unique piece of designer jewelry.
