Mostly wavy chalcedony/agate quartz lines this Mexican Trancas geode pair. The geode is partially a "mud ball" - it did not entirely turn into a geode which is a little different but not out of the norm for geodes from Mexico. Opened into two halves with a soil pipe cutter and the edges are not polished. Price for the matching pair is $10.00 plus shipping.
Origin: Chihuahua, Mexico
