Sapphire Czochralski method
RusGems offers created Sapphire, which is produced using the Czochralski method. Only this method enables creation of the large and pure crystals of recrystallized sapphire.
It is almost impossible to distinguish the crystals obtained thus from natural ones by only using simple methods (refractome-ter, polariscope, microscope, spectroscope, etc.). Crystals grown by Czochralski method belong to a group of high-quality expensive synthetic stones, which are also called recreated or cultivated stones (created or cultured gemstones).
