Welcome!
This is a well formed Dugway geode Oregon Thunder Egg, with one deeper, distinct chamber. The chamber has well formed boytroidal lumps inside with the finest coating of druzy quartz covering them. 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. An acrylic stand is included for displaying this crystal.
