An exceedingly aesthetic specimen of sharp scheelite crystals on a stack of quartz crystals capped by a gemmy, doubly-terminated one. One one side of the stack of quartz crystals you can see an arsenopyrite crystal that the quartz has grown around. The bottom side is the contact, where you can see that the arsenopyrite is intergrown with chalcopyrite. The scheelites are the characteristic color for the Yaogangxian, a sort of caramel-grey. 8.5 x 6.7 x 5.7 cm
