Vintage 16.63 Ct Emerald-Cut Green Tourmaline Diamond Ring 18K Gold & Platinum

Vintage 16.63 Carat Emerald-Cut Green Tourmaline and Diamond Ring in 18K Gold and Platinum, Circa 1970

An Art Deco–inspired cocktail ring dating to circa 1970, centred on an elongated emerald-cut green tourmaline weighing approximately 16.63 carats. 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.

The 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.

In profile, the substantial split shank opens into a raised gallery that reveals the depth of the tourmaline. The mount bears a 750 stamp and a maker’s mark.
