Black Onyx has been used in jewellery for centuries and is recognised for its deep black colour and smooth, polished surface. The stone has long been valued in both historic and contemporary jewellery for the contrast it creates when paired with precious metals.

Across many cultures, Onyx has often been associated with strength, focus, and resilience. Its dark tone and solid appearance give it a grounded and enduring character within jewellery design.

When set in sterling silver, the bold colour of Black Onyx becomes the focal point of the piece. The marquise shape enhances this contrast, creating a ring that feels both structured and expressive.
