Jamestown District, Boulder Co., Colorado, USA 6.5 x 3.8 x 2.5 cm. This specimen was collected by Richard Kosnar on April 15, 1973 in the famous Jamestown District of Colorado which is northwest of Boulder. This pegmatite region has produced some very good specimens of a few species, such as Törnebohmite-(Ce). This specimen hosts a "vein" of grey color Törnebohmite-(Ce) which is wedged ... |
