Cocktail Rings

Tanzanite & Diamond Cocktail Ring

Discovered in the 1960s, Tanzanite is found in only one place in the world. It is prized for its colour, which varies from bright blue to warm violet. This cocktail ring has been designed and crafted around a certified 7.46 carat oval cut tanzanite, selected for its rich blue hue.

The design is floral and delicate, with smaller oval cut diamonds creating a scalloped effect around the central gemstone, surrounded in turn by round brilliant cut diamonds. Split shoulders, also set with round brilliant cut diamonds, add further intricate detail.
