Moonstone is an opalescent form of Orthoclase. You will find Moonstone under the Orthoclase heading in mineral books. Orthoclase is a member of the Feldspar group which contains aluminosilicate and potassium. Orthoclase is a major rock forming mineral.

Moonstone is distinguishable by its Schiller Sheen, also known as the “floating moon effect”, adularescence or blue and white sheen. This sheen is caused by interlaid Orthoclas and Albite rectangles. If the layers of these interlaid minerals are thin, you will see a blue sheen. If the layers are thick, you will see a white sheen. Moonstone can also show chatoyancy, a narrow cat’s eye reflection.

Moonstone is a 6 to 6.5 on the Mohs Scale of Hardness.
