Andalusite is an aluminium silicate mineral that forms naturally during the metamorphism of clay-rich rocks under high temperatures and pressures. It is named after Andalusia in Spain, although the first specimens were later found to have originated elsewhere. Well-formed crystals are found in countries including Brazil, Spain, Sri Lanka, Australia and the USA. One of andalusite's most distinctive features is its strong pleochroism—it can display different colours depending on the viewing angle, often shifting between green, brown, gold, olive and reddish tones. Some specimens contain dark carbon inclusions that form a natural cross pattern, known as chiastolite, a well-known variety of andalusite. From a symbolic and spiritual perspective, andalusite is often associated with: Adaptability and resilience during times of change. Seeing situations from multiple perspectives. Balancing opposing viewpoints and inner conflicts. Encouraging clear decision-making and personal integrity. Supporting grounded spiritual growth while remaining practical. Many crystal practitioners associate andalusite with the Root Chakra for stability and grounding, while its colour-changing nature is also linked with the Solar Plexus and Third Eye Chakras, encouraging confidence, insight and flexible thinking. With a Mohs hardness of around 6.5–7.5
