The stone has a deep forest-green colour with a steely sheen. As the ring moves, vivid green flashes run along its broad, parallel facets, accentuating the length of the cut.\u003c\/p\u003e\n\u003cp\u003eThe Art Deco influence comes through in the tourmaline’s clipped corners, crisp step facets and the symmetry of the diamond shoulders. Three round diamonds flank each side of the centre stone, set in platinum over the 18K yellow gold mount. Their bright sparkle complements the long, even flashes of the tourmaline, while the cool tone of the platinum defines the diamond shoulders against the yellow gold.\u003c\/p\u003e\n\u003cp\u003eIn profile, the substantial split shank opens into a raised gallery that reveals the depth of the tourmaline.
