Hematite, Siderite, Goethite
Park and Teller Counties in Colorado are best known for producing some of the most magnificent Amazonite specimens in the world. There aren't many species associated with the Amazonite, mostly Quartz, Albite, Fluorite and sometimes Hematite. The majority of the Hematite specimens from this area are often found as pseudomorphs after Siderite. This particular specimen features a very attractive, excellent, sharp, aesthetic rhombic crystal of Siderite which has been replace by Hematite and is associated with golden-brown Goethite and minor contrasting pink Microcline. The specimen was collected by Richard Kosnar on May 28 1982 while on a collecting trip with his good friend Erberto Tealdi (former editor of Rivista Mineralogica Italiana). According to Rich Kosnar's label that accompanies the piece, it is very rare to find both Goethite and Hematite together, and this particular association is unique to the Lake George area of Colorado. A very attractive, and hard to find Hematite pseudomorph association specimen. Ex. Richard Kosnar Collection.
