Quartz ranks 7 on the Mohs hardness scale, making it resistant to scratches and suitable for daily wear. These stones form deep in the earth's crust where silicon dioxide crystallizes under specific temperature and pressure conditions. The color variations you see come from trace minerals like iron, titanium, and lithium trapped during formation.
