Fluorescent apatite gummy crystals Former private...

The term apatites commonly refers to certain minerals with the general formula Ca5(PO4)3[F, OH, Cl], in particular chlorapatite, fluorapatite, and hydroxyapatite. These minerals are themselves part of the Apatite group defined by the IMA. Apatites should be regarded as ionic structures and, consequently, are characterized by a high melting point (above 1400 °C) and notable hardness.
