History

  • The name 'onyx' comes from the Greek word 'onux', meaning 'nail', because the translucent white colour of the layers within is similar to a fingernail. Onyx is a form of Chalcedony, which is microcrystalline Quartz. It is formed in the gas cavities of lava. Onyx is black and white Agate and should not be confused with Onyx-Marble, which is Limestone. When a stone has a black base and a white top layer it is called Onyx. When it has a brown base it is called Sard-Onix and when it has a red base it is called Carnelian.

Care

  • To clean the Onyx, simply use soapy water and a soft cloth. Be sure to rinse the onyx well to remove any soapy residue. As with most other stones, ultrasonic cleaners and steamers are not recommended. It is best to store stone jewellery and the stones themselves in a fabric-lined box or wrapped in cloth separately from the others to prevent self-damage and possible scratches.
  • It is advisable not to wear jewellery during major physical activities such as exercise or sports. Avoid spraying perfume and hairspray directly on your jewellery and stones.
