Available in two sizes, it has a sleek, uniform black surface with a deep, mirror-like polish. Quick facts Stone Black onyx Composition Chalcedony (a microcrystalline form of quartz, silicon dioxide) Hardness (Mohs) 6.5–7 Color Uniform black Chakra Root chakra Traditionally used for Grounding, strength, protection Care / Water-safe Yes — durable and water-safe Meaning & history Onyx has been carved into seals, beads, and ornamental objects for thousands of years, prized for how evenly it takes a polish. Much of the deep, uniform black onyx sold today is natural chalcedony that has been dyed or heat-treated to even out its banding into a solid color — a common and long-established trade practice, and still a genuine natural mineral at its core. In crystal tradition, black onyx is associated with grounding, strength, and protection, and a large sphere is often chosen as a commanding display piece.

How to use it At six inches, this sphere is best used as a statement display piece — on a stand in an entryway, office, or living space where its size and polish can be appreciated. Many people also hold it briefly during grounding meditation before returning it to its stand. Care & cleansing Black onyx is a hard, durable stone and can be wiped down or rinsed with water and dried with a soft cloth without issue. Avoid abrasive cleaners that could dull the polish. For energetic cleansing, many people use smoke, sound, or moonlight rather than prolonged soaking. Frequently asked questions What is a black onyx sphere?
