This piece consists of a thin cut section of Satin Spar, a variety of Gypsum that is compact and fibrous. While the two "basal" faces of the piece have been polished, the edgeward surfaces have been left intact, showing these fibrous tendencies. The material is basically colorless and transparent, though it appears to be milky white in color and translucent from the side. The cut faces are still visibly scratched but have been partly polished, enough so that one can see print and images somewhat clearly through the piece if it were to be lain atop them. There is no host rock present.
