Physical properties

Formation & geological history

Tourmaline commonly crystallizes in lithium-rich granitic pegmatites and metamorphic rocks, often during late stages of magma cooling; deposits range from ancient Precambrian to much younger formations.

Uses & applications

Used in jewelry and mineral collections; gem-quality pink tourmaline is faceted or carved.

Geological facts

Tourmaline crystals can show strong pleochroism, appearing different colors from different directions.

Field identification & locations

Look for hardness, vitreous luster, and color variation; common sources include Brazil, Afghanistan, Madagascar, Mozambique, and the United States. Confirm identification with gemological testing, since color alone is not diagnostic.
