"Apatite" is a stone that is loyal and devoted to its owner. It tries to protect him from hardships, informing him of a possible dangerous situation.
This gem is one of the main sources of calcium phosphate on our planet, as it consists of phosphorus. Apatite got its name, which means "deceptive" in Latin, because of its resemblance to other gems.
It is also a mineral that is actively used by lithotherapists.
