Nanosital, lab created gemstone. It has good optical properties. Its gloss corresponds to that of the most attractive natural stones, namely sapphire, ruby and topaz, which becomes especially apparent when medium and large stones are viewed. It keeps all the best features of its prototype (color, purity, gloss and beauty), leaving drawbacks (processing difficulties, unstable color, and most important - high price) behind. During these ambiguous times we all have to make bold and innovative business moves. That's why right now is the best time to bring into the world our new material refined with your jewelry design or home decor. About NanositalTM NanositalTM belongs to material group which is called glass-ceramics. I.e. it's the composite material that contains very small (nano-sized) crystals into glass matrix. Glass-ceramics is the combination of glass and mono crystals. The glass matrix has Y-Al-Si-O and crystal phase may be different. It depends on required color: garnet, mullite, cordierite (dichroite) , etc. The last composition definitely allows achieving the best optical index. Even though there is no any combinations Pb (lead) and that's why we can make high dispersion 0,015-0,02 and refraction index (to 1,75). It's achieved because of Y and Al as in case with crystals YAG. We're improving these indexes but the color is unchangeable. For example, we produced blue and orange sapphire with density of 3,6gr/cm3 and RI - 1,75, i.e. it's like natural garnet. US@GEMS is producer and trader of created crystals for jewelry and decor. We sell created gems which have same color and properties as their natural counterparts. Our gemstones made by men with keeping Nature! We offer rough and cut gemstones.
