Moonstones can be found in several countries, but most of the Black Moonstones on the market come from India, Madagascar, Mexico, and Norway.

Moonstones are typically mined at their primary deposits which still have their original relationship with the host rock. They typically come from artisanal miners working small shafts dug out by hand.

Moonstones have a natural iridescence that is enhanced by cutting and polishing.
Moonstone is a name used to describe a variety of Feldspar minerals which show a white, silver or rainbow iridescence.  Feldspars are silicates, minerals which contain the elements Silicon (a light gray shiny metal) and Oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a Silicon atom in the center and Oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. There are six main groups of Silicate minerals, and these main groups are further subdivided into secondary subdivisions, such as Quartz and Feldspar.  Scientifically, Moonstone can be any of the following minerals: Orthoclase, Anorthoclase, Oligoclase or Adularia.
