Black Onyx Sphere Peru

Black Onyx Sphere Peru is a crystal sphere (shop SKU L05015A) on the shelves at Namaste Bookshop in Manhattan.

Onyx is a banded form of chalcedony; black onyx used in jewelry is often a dyed or uniformly dark chalcedony. In crystal traditions, black onyx is associated with protection and self-mastery. Those ideas belong to folklore and personal practice, not to any medical claim.

Natural stones vary in color, clarity, and shape, so the piece you receive will have its own character even when the weight or grade is listed.
