Fluorapatite
 | Ca5(PO4)3FCa₅(PO₄)₃F
Fluorapatite (Ca5(PO4)3F) is a fluorinated calcium phospate. These samples are on display in the Smithsonian Museum of Natural History. This sample is about 7 cm across and the gem is 51.4 carats. They are from Durango, Mexico. 氟磷酸钙（Ca₅(PO₄)₃F）是一种含氟的钙磷酸盐。这些样本陈列在史密森尼自然历史博物馆中。该样本宽约7厘米，宝石重51.4克拉。它们来自墨西哥杜兰戈。 Calcium phosphate in the form hydroxyapatite is the material from which teeth are made, and fluoridation of water is presumed to turn some of that calcium phosphate into fluorapatite. Fluorapatite is considerably harder than hydroxyapatite and is thought to provide a measure of protection against tooth decay. 羟基磷酸钙是构成牙齿的材料，而水中的氟化物被认为会将其中一部分钙磷酸盐转化为氟磷酸钙。氟磷酸钙比羟基磷酸钙更硬，并被认为能对蛀牙起到一定的防护作用。

The sample above left is fluroapatite with quartz and cookeite. The sample size is about 3x5 cm, the fluorapatite being the purple crystalline part. The sample above right is about 5x5 cm in size. The description: "This specimen is world-famous among mineral collector for its rare purple color and near-perfect shape. The color comes from impurities of manganese." Both samples are from Pulsifer quarry, Mt. Apatite, Auburn, Maine.
