apatite

Apatite is a group of minerals commonly found in many types of rocks, especially igneous and metamorphic ones. It is primarily composed of calcium phosphate, making it a key source of phosphorus, which is essential for plant growth and is used in fertilizers. Apatite appears in various colors, including green, blue, and yellow, and has a glassy appearance with a crystalline structure. Beyond agriculture, it is also used as a gemstone in jewelry and as a raw material in the production of phosphate-based products. Its stability and phosphate content make it an important mineral both biologically and industrially.
