This is a very fine Blue Dugway Geode with a Vertical Open Chamber. The single vertical open chamber nearly bisects the geode. The chamber has a lining covered with fuzzy, sometimes deep lavender crystals. The flat polished face has mystical concentric rings encircling the chamber. There is even a delicate mini cluster of crystal tightly clinging to the roof of the chamber. Also referred to as a 'Thunder Egg', this geode, as with all my Dugways, is from the finest beds of geodes in Utah known as the Juab Formation. I buy these directly from the miners who excavate them. The underside has five round felt 'feet' for resting in a display position while protecting the surface of where it is sitting.
