A large old-time combination of Calcite and Quartz from the Yaogangxian Mine in Hunan, China, mined around 2002. As the photos show there are lots of beautiful details for you to explore all over. The Calcite crystals fluoresce a pleasing reddish-pink color under shortwave UV light (see below). Good views all the way around, with excellent presentation for display as pictured. From my personal collection.
