Green onyx is an assortment of chalcedony, a microcrystalline type of quartz. What recognizes green onyx is its striking green hue, going from sensitive pastel shades to profound, energetic greens. This shading is ascribed to the presence of copper minerals inside the stone. Its name is derived from the Greek word “onyx,” meaning hook or fingernail, attributable to its customary use in making cut diamonds and appearances. The history of green onyx may be traced to several parts of the globe. It is mainly found in countries with abundant chalcedony natural deposits. Among the prominent suppliers of Green Onyx are the US, Brazil, India, and Uruguay. The slow crystallization of silica-rich fluids inside magma holes is one of the fascinating geological processes that lead to the production of the gemstone. The unique patterns and bands that set Green Onyx apart from other gemstones are eventually created by the cooling and hardening of these solutions.
