Feldspar Gem Guide and Properties Chart
Feldspar minerals are some of the most abundant minerals within the Earth's crust and are a common component of rocks. Species that are rich in potassium (K) are called potassium feldspars. Orthoclase, Microcline (Amazonite), and Sanidine are potassium feldspars. Feldspars rich in sodium (Na) or calcium (Ca) are plagioclase feldspars.
