Limonite ps. After Siderite (RARE Colorado) ex Ed Swoboda Coll.

Item Description

The Crystal Park area of El Paso County is famous for excellent amazonite and smoky quartz specimens, BUT pseudomorphs of limonite after a large sharp siderite rhomb are EXTREMELY RARE. An impressive large and sharp 7.0 cm on the diagonal rusty-orange limonite pseudo is dramatically set on the matrix of feldspar and smoky quartz crystals. Complete all-around and pristine. Exceptional perhaps UNIQUE material from the Ed Swododa Pseudomorph Collection. Ed, who lived from 1917-2013, was one of the United States most successful field collectors. He traveled worldwide and found the world's finest brazilianites in 1945. Ed purchased the Stewart, Tourmaline Queen and Pala Chief pegmatite mines and was part of the renowned "bluecap" tourmaline discovery in 1972 at the Queen. Later projects included boleite and cumengite from the Amelia Mine in Mexico, famous purple adamites from the Ojuela Mine in 1982 and wulfenite and mimetite from the San Francisco Mine in 1989. He assembled several world-class mineral collections (with the famous Alma Queen rhodochrosite), including a superb pseudomorph collection, started in about 1984 and sold in the late 1990s and dispersed in the early 2000s. This is an outstanding example from the collection. Read Ed's biography in the Mineralogical Record Biographical Archive: http://www.minrec.org/labels.asp?colid=630. Value of this amazing 360-degree pseudo?? A MUST for the Colorado or species collector.
