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. This stone has a hardness of 6.5-7, similarly to most other forms of Onyx. The color of Green Onyx is a rich, deep green and it is primarily found in Brazil, India, Madagascar, Mexico, Peru, and USA.
Green Onyx carries with it the primary properties of all forms of Onyx which are known for strength, willpower, and discipline but the green varieties stimulate these traits from the heart. It is able to soothe one's heart, bringing one to a calm emotional state. In bringing one to this state it allows for a still mind so that one may call upon their inner endurance and persistence, making both self-mastery and dreadful tasks feel like a breeze.
Green Onyx is associated with the planet Mercury, which is known to represent intelligence, elevated brain power, and enhanced memory. It is meant for anyone who wants to speak truth from the heart. This mineral opens up and actives the heart, in alignment to the brain, producing honesty and powerful realizations.
Green Onyx is also known to repel negativity from the user. It is 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 also has the effect of increased confidence. Its a very strong heart stone and will allow you to stand up and face anxiety when confronted with it, instead of allowing it to control you. Green Onyx is recommended for public speakers, politicians, or actors who are always in front of society.
