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.
