The feldspar group''s wide variety of unusual gems includes moonstone, nonphenomenal orthoclase, phenomenal and nonphenomenal labradorite, sunstone, and amazonite. Of these feldspars, moonstone is a constant favorite, while sunstone from Oregon is gaining attention as a natural and untreated product of the United States.
Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based upon feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8).

Besides hardness, the biggest difference is how the two minerals break.

When a feldspar cools, it may internally segregate into separate crystals with different properties. These are not easily distinguished, but a single stone may have layers of orthoclase, plagioclase and other feldspars. This process is called unmixing and is how blends are created. The layering of different species results in twinning.
