7.50 Carat Tanzanite and Diamond Ring in 18 Karat White Gold

A striking tanzanite and diamond ring centred with an oval-cut tanzanite weighing approximately 7.50 carats.

The tanzanite displays an exceptionally vivid blue-violet colour, shifting between rich royal blue and flashes of purple as it moves in the light. It is secured in a four-claw setting and flanked by brilliant-cut diamond shoulders totalling approximately 0.40 carats.

The substantial 18 karat white gold mount has a broad, polished profile and gives the ring a strong, luxurious presence on the hand.

The ring has been professionally cleaned and presents beautifully. The tanzanite shows no visible cracks or major damage, with only minor surface wear consistent with previous use. The stone sits very slightly off-level within the setting due to its deep, individual cut, although this is not apparent when viewed face-up. The diamonds are bright, lively and eye-clean.

A bold, highly wearable cocktail ring with outstanding colour and impressive scale.
