Composition-K[AlSi3O8], trickle. sing. Ordinary microcline rarely finds use as an ornamental stone. However, its meat-red crystals with perlite albite growths and mother-of-pearl luster on the cleavage planes are occasionally treated with cabochon or used in stone-cutting products.

Sometimes a combination of the effects of sun and moonstone was observed in the translucent varieties of microcline
