WHAT IS GREN ONYX:
Green Onyx is often mistaken for Emerald and Jade but differs in formation and structure. It is formed through the layering of Chalcedony and Quartz in a cryptocrystalline formation, whereas Emerald for example, is a Beryl formation.
Green Onyx is a term that usually refers to Chalcedony that has been dyed or
heat-treated green for aesthetic purposes, although it can also refer to Agate that is banded with white and light green.
It is primarily natural; however, the green aspect of the stone is added in once the gemstone has formed completely.
Onyx is usually seen in rich brown, white, or deep black colors, with wavy white stripes on occasion.
Green Onyx often has traces of Opalescent Moganite that give it a banded, opaque appearance.
It is most often mined in Brazil, India, Madagascar, Peru, and the USA.
