Bladed Barite crystals which have pseudomorphed to Quartz with an overlayer of micro, druze Quartz crystals. On the side of the specimen, a cross section of these pseudomorphed crystals is visible and reveals they are partially hollow. Despite the accompanying labels, no feldspar is found at the location and the habit of the crystals is clearly Barite. There are two similar specimens posted on mindat for the location both identified as pseudomorphs after Barite.
Flaws: A couple of the pseudomorphs on the dark side of the specimen are broken.
