Blue Onyx
The Playful Blue Calcite of Deep Waters
Also known as: Lemurian Aqua Calcite
About the stone
Blue onyx is a trade name rather than a single, precisely defined gemstone: it commonly refers to dyed blue chalcedony or naturally blue, banded calcite, which is not true onyx. Although onyx has been carved into jewelry, seals, and ornaments since ancient Egyptian, Greek, and Roman times, “blue onyx” has no single documented discoverer or discovery date. Chalcedony used for the dyed material comes from countries including Brazil, India, and Madagascar, while blue calcite sold under the name is quarried in Argentina, notably Mendoza Province. In modern crystal lore, blue onyx symbolizes strength, emotional balance, and confidence.

Care and handling
Blue Onyx is calcite, which is soft and reacts to acids, so keep it away from vinegar, lemon, cleaners and acidic water, and do not soak it. Wipe gently with a soft damp cloth and dry it right away. It scratches easily and can chip if dropped, so store it apart from harder stones. Avoid sudden temperature changes and strong sunlight, which may fade its color.
Individual experiences with Blue Onyx vary, and its effects are personal and not guaranteed. Use it with mindful intention, and let it invite a little play and wonder.
