RG Crystals 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).
