18.90 Carat Green Tourmaline Diamond Platinum Ring
A truly impressive cocktail ring centered by a massive 18.90-carat elongated cushion green tourmaline of exceptional size, depth, and saturated color. The richly hued gemstone is securely held in a minimalist four-prong platinum setting that allows maximum light return and showcases the stone’s natural brilliance and clarity.
Flanking the tourmaline on either side are elegant square diamonds, channel-set in a clean, geometric arrangement that adds refined sparkle and balances the bold scale of the central stone. The substantial platinum mounting weighs 22.8 grams and offers a cool, contemporary contrast to the true vivid green tourmaline.
Currently a size 7.5 and fully sizable, this ready-to-wear statement piece is ideal for collectors seeking a rare combination of substantial carat weight, strong color, and understated platinum elegance.
