Etymology
Apatite from Marina Mine, Colombia
Apatite takes its name from the Greek word “Apatein” which means wrong, mislead, or confused, chosen by A.G Werner in 1786, professor of mineralogy at the Freiberg Academy (Germany) who upon studying this gem found, that in fact, it was a new mineral but so far had been confused with others to which it is very similar.
Geological Origin
The origin of apatite is given by hydrothermal formations, magmatic and metamorphism of sedimentary basins.
False Names
