Three crystal
growth methods
01
Hydrothermal — closely mimics natural stone growth conditions. The process involves crystal growth under high temperatures and pressures
02
Verneuil Method — produces synthetic gemstones, mainly rubies and sapphires, using a non-molten dry powder mixture
03
Czochralski Method — grows monocrystals by pulling them upward from the free surface of a large volume of melt, initiating crystallization with a seed crystal
