A classic, old-time and fine German cabinet fluorite specimen with an excellent provenance. The glassy, colorless, cuboctahedral fluorite crystals on this 3-dimensional piece have a preferential overgrowth of matte-finish, light rust-red hematite. A few of the crystal faces have an additional, preferential overgrowth of sparkly, golden siderite microcrystals. This historic piece hails from the famous Harz Mountains. Ex. Bement, American Museum and Herb Obodda Collections. Obviously around 100 years old or more.
