Zircon
Zircon. (Zirconium Silicate ZrSiO4).Mohs’ hardness: 6.5 - 7.5 Refractive Index: 1.777 - 1.987
The Zircon gemstone, also know in ancient times as Zargun, or the “Golden One”, has been with us for thousands of years. Mentioned in ancient Hindu scripts, Zargun is the talisma of the travelers. She brings upon us financial success and protects us from being struck by lightning. If Zargun loses her luster overnight it is an omen of troubles ahead. The color diversity of Zircon, from yellow to brown through orange and red to green and blue is caused by trace elements, some of which are radioactive. These radioactive elements are undergoing a process called metamiction, in which their inner crystal structure is being destroyed, a rare example where a gemstone has an animated life cycle.
Zircon high refractive index and strong dispersion (or “fire”) causes her to have great brilliance. An important identification mark for all Zircons, except the green variety, is the strong double refraction easily seen under the loupe at the facet edges. The illusion of “double refraction” is actually the doubling of the facet junctions, thereby creating a line where two facets meeting in the back look either doubled or blurred when viewed from the top. Being responsive to a basic heat treatment, Zircon will glow in bright yellow or pacify in pensive blue, both considered to be the most desirable colors of Zircon.
