Nice combination of quartz and calcite in this Mexican Llano geode pair! The lining is primarily a light smoky quartz with minor chalcedony/agate. A few small quartz stalactites and a calcite cluster are present in one half. The calcite crystal was slightly cleaved when the geode was opened. The geode was opened into two halves with a soil pipe cutter and the edges are not polished. Price for the matching pair is $12.00 plus shipping.
