Black Onyx is a type of semi-precious gemstone. It is typically all-black or with white stripes and has been used for centuries as an ornamental stone. Black Onyx is composed mainly of calcite, with occasional bands of other minerals such as quartz or feldspar occurring in its structure. The distinctive banding pattern found in black onyx makes it highly valued by jewelers and collectors alike. In terms of composition, black onyx is made up of several different types of calcium carbonate crystals that are arranged in layers. These concentric layers give rise to the unique striped appearance associated with this mineral. While some varieties of onyx can be quite soft and fragile, others can have a hardness rating that rivals harder stones like diamonds. One reason it stands out is the rarity. Unlike many precious stones, black onyx isn’t just mined in one place; instead, deposits have been found in several countries around the world. The stone’s complexity also adds to its scarcity – it requires more time and effort to craft than some of its counterparts.
