What is Andalusite?

Andalusite is an aluminium silicate named after Andalusia in Spain. Gem andalusite shows strong pleochroism, flashing green and orange-brown in different directions. It is a polymorph of kyanite and sillimanite – the same chemistry with a different crystal structure – and its variety chiastolite shows a dark cross in cross-section.

Rituals & pairings

Pair Andalusite with a protection & cleansing ritual

A traditional cleansing ritual for resetting your space and feeling protected.

Traditionally paired with: White sage or palo santo smudge sticks · Dragon's blood, frankincense or myrrh incense · A white or black candle

  • Open a window, then light a white sage or palo santo stick and let it smoulder.
  • Gently waft the smoke around your crystal and through the room, corners first.
  • Light a white candle and place your crystal beside it while you set a simple intention, such as "This space is calm and protected".
  • Finish with frankincense or dragon's blood incense and let it burn down safely.

Safety: never leave candles, incense or smudge sticks burning unattended, keep them away from children, pets and anything flammable, and ventilate the room. Rituals are shared as tradition, not as a treatment.
