This calcite crystal is neat in the pictures but pictures never do justice This is one of the nicest calcite points I ve found in this location which is Wabash Indiana Although Calcite and Aragonite contain the same chemical composition they differ in crystal structure Calcite forms trigonal crystals whereas Aragonite forms orthorhombic crystals Sometimes the crystals of Calcite and Aragonite are too small to be detected and it is only possible to distinguish these two minerals by complex scientific optical tests Since the true identity of
