Zultanite is a variety of the mineral species diaspore. The stones are found in remote mountainous regions in Anatolia, Turkey. The stones are mined using traditional tools such as shovels, chisels, handpicks and carbide lamps.

The color varies in unique shades of yellowish green to purplish pink under different light sources. Sizes over 5 carats (top quality) are difficult to find. The color of Zultanite may look appealing in sizes above 3 carats. Smaller stones may look lighter in color. On the Moh's scale of hardness Zultanite is 6.5-7; specific gravity 3.40. Perfect cleavage indicates great care is required in cutting the stones. The stones are cut in oval, cushion, princess, round, concave, Portuguese round, trillions and other fancy cutting styles depending on the size, shape and quality of the rough material.
