Andalusite Plain Rondelles measure approximately 4.5-9mm, have a vitreous luster, fair symmetry, well polished bodies with some pitting due to internal features, a translucent body with consistent tone on the strand, the pleochroic gem features multiple colors of green, yellow, amber, rose and brown within each stone, and the medium to dark color saturation in this warm rich gemstone group really shows the beautiful colors in these Andalusite beads.
