White Zircon

white zircon - the ORIGINAL diamond substitute!
our zircon is a naturally occuring gemstone, not to be confused with man-made CZ (it is NOT lab created)
colors available:  

white, near-colorless, greyish-white, light champagne

and occasionally with tenebrescence, a rare property that only some zircons have (gems stored in a safe or dark area will look greyish or brownish-white when first taken out and then slowly turn into their 'normal' white color when exposed to light. This fascinating phenomenon can be repeated over and over again!!).

Frrom Wikipedia "Tenebrescence, also known as reversible photochromism, is the ability of minerals to change colour when exposed to sunlight. The effect can be repeated indefinitely, but is destroyed by heating. Tenebrescent behavior is exploited in synthetic materials for the manufacture of self-adjusting sunglasses, which darken on exposure to sunlight.​"
