Formation & geological history

Formed in lithium-rich granite pegmatites via hydrothermal processes. Usually found in late-stage crystallization environments. Famous deposits are between 100 million to 500 million years old.

Uses & applications

Predominantly used as a gemstone in jewelry and as a sought-after mineral specimen for collectors. It is also an ore source for lithium, used in batteries and industrial ceramics.

Geological facts

Discovered in 1902 and named after Tiffany & Co's chief jeweler, George Frederick Kunz. It is pleochroic, meaning it displays different colors (from pink to violet to colorless) when viewed from different angles.

Field identification & locations

Identify by its distinct pink hue, strong pleochroism, and vertical striations along the crystal length. Key locations include Afghanistan, Brazil, Madagascar, and San Diego County, USA. Fragile due to perfect cleavage; avoid heat or sunlight as it can fade.
