A wild and wide spectrum of colors—from pastel pink to grandiose green—saturate a classic cut of watermelon tourmaline in this handmade, one-of-a-kind ring. A cluster of glimmering diamonds adorns the minimalist 14k gold band, while Vanity prongs grasp the verdant gemstone like a halo of gold. The iridescent hues mimic the optical illusion created by droplets of water in cloudbursts.
