Natural Onyx Stone in Pakistan

Onyx, called Jaza in Arabic and in older Urdu writing, is banded chalcedony: fine-grained quartz laid down in straight, parallel layers. Black onyx is its solid black form, and it has been a men's ring stone for as long as anyone can remember. Most black onyx sold today is dyed agate, an old and accepted practice that still needs to be disclosed. Authentic Gems is sourcing onyx now; tell us on WhatsApp what size and shape you want.
