Black Agate is a variety of chalcedony, a microcrystalline quartz, known for its deep black color, sometimes with subtle banding or patterns. It is often opaque, smooth, and polished for use in jewelry, worry stones, or decorative items. With a Mohs hardness of 6.5–7, it is durable and suitable for daily wear.
Metaphysically, Black Agate is a grounding and protective stone, associated with the root chakra. It is believed to provide inner strength, emotional stability, and a calming energy during periods of stress or grief. Many use it to absorb negative energy, enhance resilience, and promote mental clarity. It's also thought to help with decision-making and staying centered in difficult situations.
