Collection Information

Black Onyx and banded Onyx is the striped semiprecious variety of agate, and can have a jet black appearance, a marble effect or encircled with white bands.

Black Onyx is said to be a powerful protection stone which absorbs and transforms negative energy, and helps to prevent the drain of personal energy.

In times gone by Black Onyx was worn by soldiers for protection and success in battle.

Onyx is the Zodiac Birthstone for Leo (July 23rd to August 22nd)

Onyx is also a traditional 7th wedding anniversary gift

Our Black Onyx jewellery looks striking against white clothing, but works equally well with all colours and styles.

We have a selection of both types of Onyx pendants and earrings.
