Formation & geological history

Formed in lithium-rich granitic pegmatites. The lavender-pink color is caused by trace amounts of manganese. Most specimens age from hundreds of millions to billions of years old depending on the pegmatite source.

Uses & applications

A popular gemstone for jewelry (often faceted into rings or pendants) and a collected mineral specimen. It is also a source mineral for lithium extract, used in batteries and medicine.

Geological facts

First discovered in 1902 and named after George Frederick Kunz, Tiffany & Co's chief jeweler. It is strongly pleochroic, meaning it can show different colors (deep pink to colorless) depending on the angle of view.

Field identification & locations

Identify by its distinct pink/lilac hue and vertical striations on crystal faces. Found commonly in Afghanistan, Pakistan, Brazil, and San Diego County (USA). Collectors should be careful as the color can fade if exposed to direct sunlight for long periods.
