Zultanite is a trademark for a gem variety of the mineral diaspore, mined in the İlbir Mountains of southwest Turkey at an elevation of over 4,000 feet. Depending on its light source, zultanite’s color varies between a yellowish green, light gold, and purplish pink. Its gemological name is diaspore, and it is hydrated aluminum oxide colored by manganese. It was first faceted as a gemstone in the 1980s, but was not commercialy mined until recently.Diaspore has reasonably good gemstone characteristics. It has a hardness of 6.5 to 7 on the Mohs scale, comparable to peridot and tanzanite. It has a refractive index of 1.702 to 1.750, which lies between that of tanzanite and spinel. Diaspore has perfect cleavage in one direction, making it a challenge to cut.
