Microcline feldspar is best known for its striking crystal forms and pastel colors, ranging from white and cream to delicate shades of green and pink. Collectors particularly admire the rare green variety, amazonite, with its vivid color and sharp blocky crystals. Fine microcline specimens are found in Pakistan and Afghanistan, often in association with quartz and tourmaline, as well as in classic localities such as Colorado in the United States and Russia’s Ural Mountains. With their clean forms, pleasing colors, and attractive combinations, microcline feldspar specimens are both versatile and desirable additions to any fine mineral collection.
