Where do quartz crystals actually form?+
In open pockets: vugs in limestone, gas cavities in volcanic rock, and pockets inside pegmatites. That is why digging productive crystal ground means following a vein or a pocket zone rather than sifting random soil. Loose points in creek beds are pocket material that erosion already freed.
