Black Onyx: meaning, properties and bracelet ideas
Black Onyx is traditionally associated with protection, grounding and strength. In lithotherapy, it is linked to the Root chakra and to the earth element. Its vibration is considered grounded, which shapes how it combines with other stones.
From the workshop
Black onyx is a stone I've learned to look at twice.
First, because what's sold as "black onyx" is very often dyed agate. It's still a beautiful, even black, and fairly resistant, so it's easy to wear every day. Warm water, no harsh products, and it keeps its shine.
Second, because it gets mixed up with black obsidian all the time. Same deep black, same polish… Telling them apart really takes experience. Obsidian is volcanic glass: softer, more glassy, and it chips more easily. Onyx is a chalcedony, harder and denser.
It took me a lot of practice before I could see the difference at a glance.
Black onyx is traditionally associated with protection and grounding. For me, it's above all the black that goes with everything.

Chalcedonies: quartz in microcrystals
Agates, onyx, carnelian, jaspers, tiger's eye: the same quartz, but in microscopic crystals. Their bands, patterns and sheen come from the way the silica was deposited.
