Zultanite is a transparent, Type II gemstone (usually eye-clean with some inclusions under 10x magnification) with phenomenal properties like chatoyancy (cat’s eye effect) and color change. The bigger the gem, the more striking the change of colors. Gems over 5 carats are considered exceptionally rare.
Zultanite registers 6.5-7 on the Mohs hardness scale and has a refractive index of 1.70-1.75 and specific gravity of 3.39. These characteristics make it an excellent candidate for mounting in jewelry. New, exotic and rare, Zultanite is the rising star in fine jewelry. Ask your jeweler about Zultanite.
