The basic idea in finding out an appropriate method to grow synthetic crystals for gem purposes is discussed using garnet as an example. Representative methods for single crystal growth are reviewed briefly, which includes slow cooling method, Bridgman method, Verneuil method, pulling method, zone melting method, flux method, hydrothermal method, vapour growth method, high temperature high pressure method, etc. The methods for synthesizing polycrystalline gem stones such as opal, jadeite are also discussed. There are many potential gem materials among those which have been originally developed for semiconductor or optoelectronic purposes.
