Black Onyx Split-Shank Cabochon Ring

The Black Onyx Split-Shank Cabochon Ring centres on a genuine natural black onyx, cut and polished to a deep, glossy jet black that plays beautifully against solid gold. Set as a polished onyx cabochon, the oval stone reads bold and graphic on the hand, measuring roughly 7x5mm.

A clean, stone-forward design that lets the onyx do the talking. The centre is genuine natural onyx - a chalcedony, never glass, plastic or simulated.

As is standard throughout the jewellery trade, natural onyx is colour-enhanced (dyed) to achieve its even jet-black tone - a permanent, long-established treatment. Onyx is a durable gem (about 6.5 to 7 on the Mohs scale), but to protect its polish and colour, clean it with a soft, slightly damp cloth and avoid harsh chemicals, ultrasonic and steam cleaners. Set in solid gold - never plated.

A striking, versatile gift. Prized since antiquity, black onyx is a confident, unisex classic that suits both men and women, and it has long been given to mark a seventh wedding anniversary - making this ring a thoughtful choice for an anniversary, a milestone, or simply someone who loves a bold, timeless look.
