Onyx: Meaning, Properties, and Uses
Onyx is one of those mesmerizing gemstones that’s been admired for centuries—not just for its striking beauty but also for its deep symbolism and practical uses. Whether you’re drawn to its sleek black variety or the mesmerizing bands of sardonyx, onyx has a lot to offer.
In this guide, we’ll explore the meaning behind onyx, its unique properties, and how you can incorporate it into your life. By the end, you’ll know exactly why this stone has been treasured since ancient times.

What Is Onyx?
Onyx is a type of chalcedony, which is a form of quartz. It’s known for its smooth, waxy luster and striking parallel bands, though the most popular variety is solid black.
Fun fact: The name “onyx” comes from the Greek word onux, meaning “fingernail” or “claw.” According to legend, Cupid once clipped the nails of the goddess Venus while she slept, and the Fates turned those clippings into stone—hence, onyx was born.
