Studio Margoni has a way with color and rings because they design the rings and cut the gems to order in the studio. Here a blue and green delight, the larger grass-green peridot flanked by a deep green tourmaline and accented by blue topaz, all three rose cut irregularly and set in 18K gold on a sterling triple shank: easy to wear, a visual treat, and easy to own. Measures 3/4" across x 3/4" deep, 11.50 carats total weight gems.
