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 pair of good sized and remarkably sharp rhombic crystals of Siderite which have been completely replaced/pseudomorphed by silvery-black Hematite and are sitting atop beautifully contrasting pinkish Microcline. The largestg pseudomorph measures 2.8 cm and is undamaged as far as I can tell. 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.
