Onyx, a striking and powerful gemstone, has been treasured for centuries for its deep black color and smooth, polished surface. Known for its strong connection to grounding and protection, onyx is often associated with strength, stability, and perseverance. Whether used in ancient amulets, elaborate jewelry, or decorative carvings, onyx has always held a unique place in both history and spirituality.

The Formation and Characteristics of Onyx

Onyx is a variety of chalcedony, a mineral in the quartz family. It forms in layered bands, typically in shades of black, white, and sometimes brown, though the most iconic and well-known type of onyx is black. This gemstone develops over millions of years through a process in which silica minerals are deposited in gas cavities of lava. The unique banding within onyx results from this layered formation, creating a striking contrast between the dark and lighter shades.

What makes onyx particularly captivating is its smooth, almost glass-like finish when polished. Its rich black color, sometimes with white veins or bands, gives it a dramatic and timeless appearance. This natural elegance has made it a favorite in jewelry, carvings, and decorative arts for millennia.
