Dugway geodes, found within the Juab Formation in Utah, are renowned for their diverse and striking forms. These geodes are notable for their open shells, which often have thick walls. The interior surfaces of these shells are typically coated in fine crystals that form on botryoidal, or grape-like, structures.
The Geode has a see through chamber and lots of nice, lumpy, internal surfaces covered with a field of microscopic blue druzy quartz. Also, it has been flattened on the bottom to sit flat. This quartz exhibits a unique fuzzy texture and is especially remarkable for its ability to glow under long-wave ultraviolet (UV) light, as shown in the accompanying photograph.
Frequently referred to as a "Thunder Egg," this type of geode is obtained directly from miners working in the region.
