This area of China is known for these big pyromorphite crystals that have largely been replaced by baby blue plumbogummite. Some of the pyromorphite can still be seen at the base of the crystals that were once contacted to the matrix or have broken. Much of the crystals on the top of the specimen have a skeletal appearance where as sharper more well formed ones can be seen on the underside. very cool. Solid plumbogummite!
