Its fine texture also makes it ideal for carving, making it a favoured material for today’s lapidaries. In the pin by designer S usan 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, why not consider onyx?
