Andalusite is a relatively unknown gemstone, but it is also one of the most unique gemstones on the market. Andalusite is known for its pleochroism, meaning that the gemstone exhibits different colors in different viewing directions. It can be red, brown, green, yellow, or a combination of these colors depending on the viewing angle. In addition, Andalusite can exhibit a bicolor effect by exhibiting two different colors in the same direction. This is your chance to own a unique gemstone.
