Andalusite is best known for its strong pleochroism and it's unusual color. It isn't immediately considered to be a "color change stone" but it frequently shows two or more colors at the same time. Even the rough crystals will often show green in one direction and red in another. The color of andalusite beads is quite difficult to match on any any standard color chart.
Andalusite is sometimes called "The Seeing Stone" because it is used inmetaphysical works to calmly see the various parts of one's character without bias. Used to encourage one to look at issues rationally by helping one to see the various sides to a problem or situation without judgment or fear. It also helps one to realize the self-sacrifice is okay, but never required, and it is quite useful for scrying.
