We report the growth of cerium-doped multicomponent garnet (Ce/GAGG) single crystals based on crystal pulling from a melt using a cold container without employing a precious metal crucible. This novel method is described in detail. We measured the optical, luminescence, and scintillation characteristics of several samples cut from three crystals and compared them with a commercial Ce/GAGG crystal. The best samples from the set are fully comparable in all characteristics with the commercial reference crystal, demonstrating the practical potential of this method. Avoidance of an expensive precious metal crucible in this method makes crystal growth much more economical.
