Item Description

Here we have a wonderful old geode labeled as coming from Peaksville in the far northeast corner of Missouri near Hamilton in far western Illinois (near the Illinois/Iowa border on the Des Moines River). You don't see a lot of these on the market these days, and I can't remember if I've ever seen anything labeled as coming specifically from Peaksville before. This piece features a beautiful group of sharp, well-formed, pink colored scalenohedral Calcite crystals sitting in an open geode lined with smaller white "dogtooth"-shaped Calcites. The other half of the geode features just the little white Calcites. The largest Calcite crystal measures 3.3 cm long. I don't know what is causing the pink color in the Calcites, whether it is manganese or another chromophore. A great old-time Midwest Calcite specimen from this uncommon locality. From the collection of well-known collector and dealer, Richard Kosnar (1946-2007) of Black Hawk, Colorado who was the namesake for the phosphate species, Kosnarite.
