Rose quartz is formed in large veins within volcanic rocks. It forms at high temperatures deep within the earth, while most quartz forms at much lower temperatures from silicon-rich solutions. Rose quartz forms as magma slowly migrates up through the Earth's crust and cools miles below the surface (unlike an eruption that reaches the surface).
