Hematite after Siderite with Goethite on Microcline! (ex Rich Kosnar Collection)

Item Description

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 pseuomorphs after Siderite. This particular specimen features a few very attractive, excellent, fairly sharp, aesthetic compressed rhombic crystals of Siderite which have been replaced by Hematite and are associated with golden-brown Goethtie and on contrasting pink Microcline.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 the Rich Kosnar, it was very rare to find both Goethite and Hematite together, and this particular association is unique to the Lake George area of Colorado. Kosnar's handwritten label is still glued to the base of the piece. A very attractive, and hard to find Hematite pseudomorph association specimen.
