Im cutting a synthetic material called cristinite, here is a description.
After 10 years of research and developement, an innovative Australian company, Advanced Crystallisation technology Pty Ltd has released a new and unique gemstone - Cristinite.
Displaying all the qualities and characteristics of beautiful gems, this newlt created gemstone, Cristinite has proven to be a must have in the collections of all who have seen it.
Cristinite has been examined and cut by expert faceters in Australia, USA, Sri Lanka, Thailand, and Korea without exception, they found it to be a wonderful gemstone that facets very easily and polishes to a fine vitreous luster.
Suitable for most jewelry settings, it is tough and very workable, making it an ideal gemstone for both the amateur and profeesional gemcutter alike.
Its general specifications are:
Hardness: 6.5 - 7 Mohs scale
Refractive index: 1.61-1.63
Specific gravity 2,6- 3.6
