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
from Brazil, and large quantities were needed, as just about EVERY radio needed at least one.
A Google search will tell you more if interested.

Aren't crystals quartz, how do you "grow" them?
