7 Species on one specimen! (Cerussite, Rosasite, Azurite, Smithsonite, Barite, Galena and Quartz) (ex Rich Kosnar Collection)

Item Description

Without a doubt, this is one of the more impressive association specimens I have seen not only from Leadville, but virtually any Colorado locality. Leadville is well known for its Silver deposits, but the secondary ore minerals from the Sherman mine are beloved by Colorado collectors. This piece features more associated species on the same specimen than I have seen from the Sherman mine. It features tiny white "snowflakes" of reticulated Cerussite lightly dusted with Rosasite which are associated with Azurite along with crystals of Smithsonite plus golden Barite crystals, Galena and Quartz. I spent nearly 30 minutes with this piece under the microscope. It's an incredibly fun specimen to view under high magnification, and an AMAZING association specimen from one of the most storied mining districts in Colorado. Colorful secondary ore specimens are not the first thing that comes to mind when one thinks of Colorado, and this piece is about as rich as it gets when it comes to species. This specimen was collected in 1980, and stands as one of the most interesting pieces I have seen from Leadville. Valued at $800 in Richard Kosnar's Colorado collection catalogue.
