This specimen consists of a polished section of an Andalusite crystal. It is of the variety known as Chiastolite, which is characterized by a dark lines that intersect the crystal at 90-degree angles, creating a "cross". The piece is in very good condition, as only a small amount of damage is visible, and what crystal form it has is reasonably good. The two "basal" faces of the piece have been ground smooth and polished to show off the cross and the resulting quadrants of material that have a pale brown coloration with a pinkish tinge. It is nearly opaque at its center, but the edges of each quadrant are translucent and even dimly transparent to a degree. There is no host rock present, of course.
