Andalusite (Spain) Faceted 4mm Rondelle Beads, 16 inch strand
Andalusite gemstones are remarkable for their fascinating color habits and very strong pleochroism, which can cause a muliticolored effect of shades of yellow, olive-green, and reddish-brown within a single gem. Although Andalusite as a mineral is not uncommon, the transparent variety used as a gem is very rare. Another important form of Andalusite that is entirely different is the mostly opaque Chiastolite variety, which is known for its unique cross-shaped design within the body of a crystal.
