2.1" Fluorescent Chiastolite Andalusite - Kola Peninsula, Russia

This is chiastolite, a variety of andalusite that often features a distinctive cross-shaped association of chiastolite and graphite. How exactly it forms is debated, but it is widely accepted that the shape is a result of impurities at the corners of the rapidly forming andalusite crystals.

These cross-shaped specimens have been collected for hundreds of years. Chiastolite was distributed throughout Europe in the 1600s by pilgrims as an amulet or souvenir upon their return from Santiago de Compostela, Spain. These specimens would have come from Asturias, Spain, a site that produces an abundance of chiastolite.

One edge of this specimen has been cut flat. Under short-wave UV light, the chiastolite fluoresces orange.
