Mexican “Llano” geodes are a new geode being mined in Chihuahua, Mexico, approximately 200 miles south of El Paso, Texas. Jointly named by the ranch owner in Mexico and Geode Gallery LLC in late April 2015, these geodes contain hollow cavities that contain clear to very light blue quartz linings that ranges from all sparkly, crystalline quartz to primarily an agate/chalcedony and some also contain drusy coated quartz scepters of various lengths and thicknesses. Some light to medium smoky quartz lined geodes have been encountered as well. These geodes also frequently contain calcite in their cavities with some scalenohedral (dogtooth) and rhombohedral calcites sometimes being up to 1 inch (2.50 cm) on edge. Approximately 80-90% of these geodes fluoresce bright green under shortwave ultraviolet light, and the geodes containing agate/chalcedony also fluoresce a light green/creamy white color under longwave ultraviolet light.
All of the geodes on this page are already opened Mexican “Llano” geodes. Most of the pairs have been opened into two halves with a soil pipe cutter and the edges are not polished. Please see the item description for each geode for more information. For whole (un-opened/rough) guaranteed hollow Llano geodes, please visit our Whole Mexican Llano Geodes page.
