Andalusite Gemstone - Gemstones TV

Andalusite derives its name from the Spanish province of Andalusia, where it was first discovered in the 18th century. This gemstone primarily forms in metamorphic rocks under high-pressure conditions, often in association with minerals such as mica, quartz, and feldspar. Its formation occurs through the crystallization of aluminum-rich minerals subjected to intense heat and pressure over millions of years.
