Estate 18K Large Rectangular Watermelon Tourmaline Diamond Cocktail Ring 46.45ct

A bold and unmistakably individual cocktail ring, centered by an extraordinary rectangular-cut natural watermelon tourmaline displaying vivid, layered saturation from deep raspberry to olive green. The scale alone makes a statement, but it’s the organic color zoning and transparency that give the stone its presence—completely natural, completely unrepeatable. Set in 18 karat yellow gold, the mounting is substantial yet refined, with diamond-set shoulders that add just enough brilliance without competing with the tourmaline. This is the kind of piece that doesn’t follow trends—it stands apart from them.
