Onyx is a rare, semi-precious stone which has been traditionally used in jewelry making, and is believed to relieve anxiety and boost energy.

This stunning stone is used in different spaces such as baths, bars and kitchens and due to its transparency can be backlit for a calming luxury effect.

With its delicate, glamorous look, unique veining and texture and a wide range of colors, onyx is the perfect choice for those wanting to add a touch of nature and color to their space.
