This is a natural quartz crystal, from Brazil, with its faces polished to improve the visibility inside. It contains multiple thin phantoms of fine-grained white quartz sand down the left side. The back of the crystal is coated in the material you see inside, which may be clay, and has a pinkish brown tinge. There are rainbows on some of the shiny 'plates' inside.
