All of the geodes on this page are matching Utah Dugway thunderegg geode pairs. Many of these pairs also fluoresce bright green under shortwave UV (ultraviolet) light in addition to containing a hollow cavity lined with quartz and/or chalcedony. Some of these pairs are opened with a soil pipe cutter and are not polished while others may be cut/polished. Please read the item description for more details. You will receive both halves listed for the price. For whole (un-opened) Utah Dugway Thundereggs, please proceed to the Whole Utah Dugway Thunderegg Geode page.
UPDATE August 2016 - Any updates to this page will be very limited in the future as the primary Dugway geode claim owners recently lost their claim and commercial mining is no longer taking place. As a result, we are no longer able to acquire quantities of these geodes for resale. When they are gone, they are gone!
