    Product group:
    Synthetic corundum is produced from pure alpha aluminum oxide, Al2O3 free from potash (corresponds to white sapphire, which is known as walderite) in an oxyhydrogen flame. Lab-created sapphires are made using corundum, just as the natural gemstone is. However, they are created in a laboratory and grown under carefully controlled conditions, simulating the high pressure and heat of the earth to replicate a natural sapphire. The heat used to create them comes from a machine. Lab-created sapphires do not scratch or chip more easily than the natural stones and are valued for their quality.
    Product purpose:
    Synthetic corundum
    is one of the best imitation of natural colored gemstones, with a unique  characteristics.
    Gemological characteristics:
    Color, luster, hardness, density are very close to natural stones.
    Advantage:
    The color is very even and stable at high temperatures, which gives it an advantage in comparison with many natural and synthetic stones.
