Physical properties

Formation & geological history

Tourmaline crystallizes in granitic pegmatites and sometimes metamorphic rocks as silica-rich fluids cool; deposits range from ancient to geologically recent. Pink color commonly comes from trace manganese.

Uses & applications

Faceted rubellite is used in jewelry and collected; lower-grade tourmaline may be used as mineral specimens.

Geological facts

Tourmaline crystals often show strong color zoning and can become electrically charged when heated or rubbed.

Field identification & locations

Look for elongated, striated crystals and test hardness and optical properties; common sources include Brazil, Afghanistan, Nigeria, and Madagascar. A gemologist can distinguish it from similar pink gems.
