Feldspar is a group of common, rock-forming minerals with 19 member species. These minerals are mostly colorless, white, off-white, light brown or gray, but one can find almost any color among the feldspar members.
Certain potassium-rich feldspars may be a salmon to pink color.
A certain variety of the mineral microcline called amazonite is turquoise to greenish blue.
A certain variety of the mineral anorthite called labradorite is nearly black with a dark blue, green, red and gold sheen or iridescence (schiller).
The well-known moonstone is another variety of some of the feldspar minerals with its pale to creamy color and iridescence. Sunstone is a peach-colored variety of the mineral albite that has a similar luster.
