This small specimen consists of a partly-cut and -polished slab of Chiastolite, a variety of Andalusite. It has a rounded, warped oblong shape and shows the "quadrants" that are the primary characteristic of this type of Andalusite. Its color is brown with a hint of pink, and the intersecting lines that extend through it are black. The cut surfaces are polished to a high sheen, but the edgeward surfaces have a dull waxy luster. There is no host rock present.
