A superb, large, on one side terminated, rich forest-green apatite crystal from the Bear Lake Diggings at Tory Hill, Ontario. The sharp crystal beautifully translucent. The crystal has textbook crystal form and is nicely accented by the sidecar crystal. We must expect that, as with most of these, the super luster has been enhanced by Krylon, sprayed on the crystal as a preservative.


Apatites are calcium phosphates with fluorine, chlorine and hydroxyl group, Ca5 (PO4) 3 (F, Cl, OH). We distinguish 3 types of apatites: Fluorapatite, chlorapatite and hydroxylapatite, of which fluorapatite is the most common. Apatite is a type of phosphate mineral that can occur in nature in a whole range of colors depending on its chemical admixture, through green, yellow, purple, colorless, brown, gray, pink to blue. Apatite is a mineral that is formed by crystallization from magma or from accumulated residues of organic substances, so-called phosphorites. It is a very abundant accessory mineral, which is one of the basic components of rocks. It is the most abundant phosphate in the earth's crust. It occurs in very wide conditions from magmatic activity to sedimentation. It can be granular, acicular, earthy, in hexagonal crystals or in spherical concretions.
