Calcite is the primary mineral to be found in rock formations such as limestones and stalagmites (found in caves). Green calcite is considered to be a very gentle healing stone that amplifies psychic abilities; therefore it has been used often in prayers and divinations. A must have for you or your child’s rock collection!
