Onyx Gemstone Beads

Black Onyx is highly esteemed in the world of gemology for its rich, deep color and fine crystalline structure. Scientifically, Onyx is a variety of the silicate mineral chalcedony, formed by the deposition of silica at low temperatures in gas cavities in lava. This results in its unique bands of color, which can range from white to almost every other shade, often layered in striking, contrasting patterns.

Facts: Black Onyx has been used since antiquity, cherished not only for its beauty but also for its purported protective properties. The Romans, in particular, crafted seals, amulets, and rings from Onyx. It was also popular amongst the Greek and Egyptian civilizations for stone carvings and cameos, where its layered colors were ideal for creating images with depth and contrast.

Metaphysical / Holistic: Black Onyx is believed to bring strength, endurance, and perseverance to those who wear or carry it. It is also thought to help individuals face their fears and build self-confidence.
