Synthetic nano crystal gem Color Change Stone In Oval Shape Sized 8mm

Nanosital is an optically transparent polycristalline material that is formed by the crystallization of glass with corresponding chemical composition and has higher physical and chemical properties than the original glass.
Nanosital is one of glass-ceramic materials, which are known for more than 50 years and have a wide range of compositions and applications. Rusgems has adapted existing technology to create a material specifically optimized for jewellery. As a result a multi-component high temperature composition on the base of two main oxides – SiO2 and Al2O3 – was obtained. It is well-known that the above-mentioned oxides are key components of most natural gemstones. The rest of Nanosital's components are picked to approximate the maximum required optical characteristics as well as density and hardness. Our technology allows us to vary components of composition quite widely. As a result Nanosital that is absolutely identical to its natural counterpart can be produced each time.

Our innovative technologies also allow us to obtain more sophisticated Nanosital colors, such as Nanosital that changes its color depending on the lighting. Such stones look one way in the sunlight and differently in artificial light inside the room.
