There are apatites of various colors depending on their composition, the most common are blue, brown, green and colorless apatite. This mineral is usually found in the form of hexagonal crystals, but also in the form of nodules.
Due to its high phosphorus and phosphate content, apatite is often used in the manufacture of mineral fertilizers and other products such as matches.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
