Black Onyx Cabochons

Interesting little black Onyx cabochons, perfect for jewellers. These tiny stones are ideal for rings, earrings, pendants, or anything else you like!

Black Onyx can look great with silver and gold alike - it is a timeless stone and was used heavily in Victorian and Georgian jewellery.

  1. Jellen

    I needed some flat Onyx Cabochons for Men’s signet rings that I’m making.
    These are perfect – exactly the correct size as stated, and fit neatly into my settings.
    I would buy these again.
