Gorgeous blue color in these 100% natural apatite beads.
Apatite is a phosphate mineral found in igneous, metamorphic, and sedimentary rocks. The most prolific deposits of apatite are found in ancient marine and lakebed environments and consist of mineralized debris from water-dwelling organisms. Apatite gemstones can vary from translucent to opaque and with vivid green, yellow, and blue colors, depending on their chemical composition. It is commonly used as an index mineral because pure apatite is near a perfect five on the Mohs Hardness Scale.
