This invention relates to a method of growing a single quartz crystal stone. In particular, a method for hydrothermally growing a quartz stone from a quartz seed is disclosed. A substantially stress-free quartz stone is grown in an autoclave by clamping a quartz crystal seed plate in a clip so as to...

Beschreibung
Zusammenfassung:	This invention relates to a method of growing a single quartz crystal stone. In particular, a method for hydrothermally growing a quartz stone from a quartz seed is disclosed. A substantially stress-free quartz stone is grown in an autoclave by clamping a quartz crystal seed plate in a clip so as to permit substantially unobstructed growth of the stone in the plane of the seed plate, and growing at least a portion of the stone through at least one aperture formed in the clip.
