Formula:
Al2(SiO4)O
Name:
Named for the Greek chiastos, meaning cross. The name is pronounced with a hard 'ch', giving 'kahy-as-tl-ahyt'.
A variety of Andalusite
Crystals of andalusite containing cross-shaped inclusions of carbon. Common in some metamorphic rocks.
Known from the late 1500s, and called 'lapis crucifer' (cross stone) in Latin texts. It was popular with religious pilgrims in northern Spain. The publication Metallotheca (Mercati 1717) which was started about a century before it was published, includes an excellent engraving of some crystals.
