How do they make a clear quartz crystal gem faceted?

Just wondering because i bought a necklace but now i am wondering if it was better to just buy the natural rock on its own unheated and untreated and i dont know about this stuff

You can cleave it along the crystal planes, that’s what makes it faceted. Then they polish it with various diamond wheels and pastes to make it really clear and pretty.

I’d buy one from someone, experts with machines are far better/faster than you would be, unless you like to experiment and DIY
