Chemical Formula: (Ca,Na)Al1-2Si3-2O8; Hardness: 6 - 6.5; Member of: Feldspar Group; Labradorite is a plagioclase feldspar which shows adularescence (a white or bluish light seen when turned). This optical effect is so unique to labradorite that it has been termed "labradorescence". It is the result of diffraction of light in the layers of rock.
