APATITE AND ORANGE CALCITE
The name apatite comes from the Greek word apatein, meaning to deceive, because it’s often mistaken for many other minerals. Apatite is actually a group of phosphate minerals, usually referring to fluorapatite (if fluorine is the primary ion), chlorapatite (if chlorine is the main ion), and hydroxylapatite (if the hydroxyl group is dominant). Apatite is the defining mineral for value 5 on the Mohs scale.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). Calcite is the defining mineral for value 3 on the Mohs scale of mineral hardness.
This is a rare, dazzling, natural combination of electric blue apatite and brilliant orange calcite (also with a bit of tan colored calcite and a few geodic pockets (one with drusy quartz)) is from Brazil.
