Very nice quality clear quartz lined Keokuk, Iowa area geode pair complete with numerous calcite crystals especially in one half. The calcites are the typical rhombohedral habit and are up to 2 cm (0.8 inch) across. Some slight contacting is observed to a few calcites right along the edge of the geode but otherwise no damage. The geode was opened into two halves with a soil pipe cutter and the edges are not polished. Price for the matching pair is $20.00 plus shipping.
