A tiny seed crystal is suspended in a super-saturated solution. That is how they are pure and the molecules are all aligned. One of the many links on the subject: http://chemistry.about.com/cs/growingcrystals/a/aa012604.htm 73, Bob WW3QB Aren't crystals

Most quartz today is 'grown' rather than mined. It is grown under high heat and pressure in an autoclave (pressurized heater!) The process is about the same as the 'natural' method, but speeded up. I think the process was 'invented' during WW II when natural quartz was no longer available
