Facts and figures about Onyx.

 

 

Onyx: Black Magic:

In jewellery design as in fashion, colours look crisper against a background of black and black and white always looks right. In fine jewellery, the black backdrop is often supplied by onyx, a chalcedony quartz with a fine texture and black colour. Some onyx also displays white bands or ribbons against a black background. If the layers are even, this type of onyx can be carved into cameos.

 

Onyx was very popular with the ancient Greeks and Romans. The name comes from the Greek word 'onux', which means fingernail. The story is that one day frisky Cupid cut the divine fingernails of Venus with an arrowhead while she was sleeping. He left the clippings scattered on the sand and the fates turned them into stone so that no part of the heavenly body would ever perish. True, black isn't normally the colour one associates with fingernails. (Did Venus wear Vamp?) But in Greek times, almost all colours of chalcedony from fingernail white to dark brown and black were called onyx. Later, the Romans narrowed the term to refer to black and dark brown colours only.

 

Onyx which is reddish brown and white is known as Sardonyx. Sardonyx was highly valued in Rome, especially for seals, because it was said to never stick to the wax. Roman General Publius Cornelius Scipio was known for wearing lots of Sardonyx.

 

Black onyx especially shines when used a backdrop for colour play. Its fine texture also makes it ideal for carving, making it a favoured material for today's lapidary artists. In the pin by designer Susan Helmich above, a carved piece of onyx with threads of white provides a stunning backdrop for a flash of colour. Onyx was often used as the perfect foil for carved rock crystal or the drop dead red of rubies in Art deco designs. It is also popular in Marcasite jewellery. So if you would like to add a little black magic to your jewellery design, consider onyx.
