    Description

    What is nanocrystal Emerald : The crystals grown in amorphous substance by high-temperature synthesis at 1500-1750°C. The chemical composition of these materials is a mixture of oxides including silica, zirconia, alumina, zinc, lithium and magnesium oxides. Nano sized crystals are homogeneously distributed in amorphous matrix.
    Nano Crystals
    are a new type of created gemstone made especially for jewellery. The colour is homogeneous, meaning that if you bought 100 emerald green
    nano crystal
    stones, the colour would be exactly the same in every stone. The material has been created with precious metal clay in mind, so any size gem should be kiln safe and blow torch safe without colour change or damage.
