Hematite pseudomorph after Siderite

Item Description

The Lake George area of Colorado is 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 the Lake George area are often found as pseuomorphs after Siderite. This particular specimen features a notably large and remarkably sharp single rhombic crystal of Siderite which has been completely replaced/pseudomorphed by silvery-black Hematite and is aesthetically sitting atop beautifully contrasting pinkish Microcline with Smoky Quartz and even minor Fluorite. The pseudomorph is undamaged as far as I can tell, and measures 4.9 cm, which is notably large for the material, as I haven't seen many in this size from the area. The specimen was collected by Richard Kosnar in the Summer of 1977. A very attractive, and hard to find Hematite pseudomorph from this historic area in Colorado. Valued at $750.
