Hematite after Siderite on Microcline (ex Dr. Wouter van Tichelen Collection)

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 pseudomorphs after Siderite. This particular specimen features a gorgeous, aesthetic group of excellent, sharp, rhombic crystals of Siderite which have been replaced by Hematite and are sitting atop beautifully contrasting pink Microcline. The largest pseudomorph measures 1.1 cm across. The most significant aspect of this piece is how SHARP and well-defined the pseudomorphs are. They are typically much more rounded and not nearly as distinct as what we see on this specimen. This piece was collected by Richard Kosnar in the summer of 1978. A very attractive, fine quality, and notably hard to find Hematite pseudomorph from this historic mineral producing district in Colorado. From the worldwide pseudomorph collection of Dr. Wouter van Tichelen.
