This 6.55-carat tourmaline showcases a natural gradient from ocean blue to verdant green—a seamless transition that exemplifies the finest bi-color material. Precision-cut in a balanced cushion shape, the gem offers VVS clarity and strong face-up brilliance. Untreated and sourced from Afghanistan, this stone speaks to the diversity and unpredictability of tourmaline’s crystal formation. Tourmaline has long been associated with creativity and emotional balance, and stones with distinct bi-color zoning are increasingly prized by collectors for their natural artistry and rarity.
