Orthoclase Gemstone Information. About Orthoclase-History and Introduction. Orthoclase is a rare gemstone that belongs to the feldspar group, which also includes moonstone, amazonite, spectrolite and labradorite. Therefore, orthoclase is sometimes also called K-spar.Orthoclase gemstones are typically champagne yellow, golden yellow or greenish, though they can be other colours.rthoclase Gemstone Information.

Typically, potassium feldspars tend to have more pink and reddish hues, while plagioclase minerals usually range from white to gray. However, the hues of both mineral groups overlap, so color is seldom definitive.uartz: Quartz is a common mineral in many metamorphic and felsic igneous rocks that, like the potassium feldspars, also has a non-metallic luster and hardness greater than glass. Unlike the potassium feldspars, however, quartz does not exhibit cleavage, which easily distinguishes it from feldspar minerals.
