Is onyx black or blue? The answer is that onyx is primarily known for its black color, although it can also appear in other shades, including white, brown, and even blue. Onyx is a type of chalcedony, a mineral in the quartz family, and its color variations depend on impurities and the formation process.
What Is Onyx, and How Is It Formed?
Onyx is a banded variety of chalcedony, which is a cryptocrystalline form of silica. It is composed of fine intergrowths of quartz and moganite, both silica minerals. The most common form of onyx is black, but it can also be found in other colors due to the presence of impurities or trace elements during its formation.
-
Formation Process: Onyx forms in the cavities of lava, where silica-rich waters deposit layers of chalcedony over time. These layers can vary in color and thickness, resulting in the characteristic banding of onyx.
-
Color Variations: While black onyx is the most well-known, onyx can also be brown, white, or even blue. The color depends on the minerals present during its formation.
Is Blue Onyx Real or Dyed?
