A beautiful onyx and diamond plaque ring in 14ct white gold. The oval faceted onyx features a central old mined cut diamond that sparkles beautifully against the jet-black onyx. The Art Deco ring is in good antique condition, with minor indentations on the gemstone near the claws and light tarnishing to the shoulders from age. This does not detract from the piece's overall striking beauty.

We offer a ring re-sizing service by our antique specialist for a small fee, starting at £45.
Most of our rings can be resized, but if they can’t we will stipulate this in the description.
As a rule we will only alter a ring by three UK sizes. If you would like to size a ring more than three UK sizes (either up or down) please contact us on a case by case basis and we will try and accommodate you as best as possible.
We do not offer refunds on altered pieces, so please make sure you love your new piece before you purchase.
Sizing takes approximately 1-2 weeks. Please add the size you require as a note at checkout.
