Quartz will not crystallize from a melt or from the vapor phase. You get amorphous fused silica or amorphous fumed silica, respectively. Natural or cultured, quartz crystallizes from hydrothermal solution.
There are at least nine major cultured quartz growers - Toyo, Tokyo Denpa, Sawyer Research, Syquartz, Rakon, Hoffman Materials, Nihon Dempa Kogyo, Kinseki, and Daishinku.
