Physical properties

Formation & geological history

Formed in granitic pegmatites through hydrothermal processes. As late-stage magma cools, water-rich fluids concentrate rare elements like lithium and boron, allowing large crystals to grow in pockets. These can range from Proterozoic to Cenozoic geological ages.

Uses & applications

Used primarily for gemstone jewelry, metaphysical collecting, and mineral specimens. High-purity pink tourmaline is faceted as 'Rubellite', while matrix specimens are popular for cabinet displays.

Geological facts

Tourmaline is pyroelectric, meaning it can generate an electrical charge when heated. The pink color is usually caused by natural irradiation or trace amounts of manganese within the crystal structure.

Field identification & locations

Identify in the field by looking for elongated, striated (lined) prismatic crystals embedded in white quartz. Found globally in pegmatite-rich regions like Minas Gerais (Brazil), San Diego County (California), and Afghanistan.
