Onyx

Onyx is the black banded chalcedony, smooth and heavy, that jewellers have used for signet rings and mourning pieces for centuries. We stock black onyx tumbles and a green banded variety, onyx eggs, bead and chip bracelets, point necklaces, heart earrings, a pendulum, a tree-of-life suncatcher and small carvings such as an onyx mouse. Several pieces come on cards for particular occasions, including a grief set. Traditionally onyx is a stone of strength and self-control, and the plain black looks smart against silver.
