Product Highlights
About the Product

One of the most distinctive characteristics of onyx jewellery is the deep black colour that the gem brings to the table. This intense and opaque black creates a sense of mystery, making it a popular choice for modern-day jewellery pieces. The velvety blackness of onyx evokes a sense of power and strength making it a preferred gemstone for unisex ornaments.

  • Black Onyx Baguette measures 14x10mm with a Flat Inlay Cut.
  • The signet ring is unisex and can be worn by both men and women.
  • Crafted in silver, the black onyx stands out as a solitaire gemstone.
  • The contrasting colours of the gemstone and the polished metal, present the ring in a black-and-white theme.
