An obsession with Maria Joan Dixon's velvet painting of Hubble Telescope's View of Space influenced early ideas about gemstones floating in a contrasting concrete matrix. Since then, different colorways have been developed, including white, black, pink, and powder blue.
As a building material, gemstone terrazzo can be used in all of the same ways as concrete or "regular" terrazzo. It can be precast in to any shape and comprised of any combination of minerals. White uses Lapis Lazuli, Tiger's Eye, Rose Quartz, Amethyst, Amazonite, Calcites, Agates, Fluorites and Pyrite, among other semi-precious stones.
