cat eye Zultanite

The GIA (Gemological Institute of America) classifies Zultanite as a Type II transparent gemstone, meaning that it is usually eye-clean (no visible inclusions when the gem is examined approximately 6 inches from the naked eye) with some inclusions visible under 10x magnification. Inclusions are tiny natural features that grow within the crystal during a gem's formation within the earth. Mostly microscopic in nature, inclusions are a fascinating hallmark of authenticity, recording a gem's natural relationship with the earth. They are also extremely useful to gemologists when identifying natural gemstones from synthetics and imitations.Zultanite registers 7 out of 10 on the Mohs' Hardness Scale (a system devised in the 18th century by a Viennese mineralogist Friedrich Mohs to measure the ability of a gem to resist surface scratching), has a refractive index of 1.75 and specific gravity of 3.39. Unless you're a gemologist, these numbers won't mean much to you, but these characteristics make Zultanite an excellent jewelry gemstone. As 100% natural gemstone, Zultanite is one of the few gems that have no known enhancements or treatments.While the newness of Zultanite means that it has had little time to accumulate legends and lore, for those interested in the esoteric properties attributed to gemstones, some people believe Zultanite can assist in the development of psychic power, astral force, ambition, intellect, desire and emotions based on intellect and touch.
