People think Onyx is a black gemstone. But the truth is it has a large colour varsity such as green, pink, brown and colorless. Its commonly worn as a piece of jewelery due to its likeness to that of Jade and Emerald, but actually has a much more powerful effect on the body when it comes to blocking negativity. Wearing Green Onyx has the effect of increased confidence and it’s a very strong heart stone. Green Onyx is primarily found in Brazil, India, Madagascar, Mexico, Peru, and USA.
