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.

Quartz: 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.he potassium feldspar group is composed of three mineral polymorphs, each having the same chemical composition, but slightly different crystal structures. Technically these are distinct minerals, but their physical properties are so similar that they are usually only identified as âpotassium feldsparâ in the field.
