Physical properties

Formation & geological history

Quartz crystallized in silica-rich veins or pegmatites, with tourmaline needles growing within it as the minerals formed. Such deposits occur in rocks of many geological ages.

Uses & applications

Used as a decorative or collectible crystal point and in jewelry; quartz also has extensive industrial uses in glass and electronics.

Geological facts

Black tourmaline needles enclosed in quartz are commonly sold as “tourmalinated quartz.”

Field identification & locations

Look for dark, slender inclusions within clear or milky quartz; the specimen’s polished shape is human-made, but the material is geological. Found in quartz veins and pegmatites worldwide, including Brazil, Madagascar, and the United States.
