Goethite pseudomorph after Calcite with Goethite and “Onegite” / Locality - Goethite Hill, near Lake George, Park County, Colorado


Shipping to United States: Free

This piece was collected by my father on Goethite Hill on the 4th of July, 1980. The piece is most interesting because it is actually a Goethite pseudomorph after a Calcite crystal (but it could possibly be replacing Quartz) which is accented with small metallic golden-brown blades and “sprays” of Goethite, and a few Onegites which measure up to 7 mm. This is a unique piece – and as it says on my dad’s collection label, “only such specimen seen”. This is a superb specimen from one of the most storied and well known districts in Colorado. The pegmatites near the Lake George area of Colorado have produced what most collectors and dealers consider to be some of the finest crystallized Goethite specimens from the standpoint of superb color, top quality, large crystals, wonderful display specimens and excellent associations. This is a totally one-of-a-kind specimen, and definitely not replaceable on the market.
