Forms in metamorphic environments and hydrothermal veins where silica-rich solutions precipitate, often incorporating tiny scales of mica or other minerals.
Uses & applications
Widely used in jewelry, decorative carvings, beads, and as a popular tumbled stone for crystal healing and mineral collections.
Geological facts
The characteristic shimmering effect, known as aventurescence, is caused by light reflecting off tiny flat inclusions trapped inside the quartz.
