Bournonite and Muscovite    Yaogangxian Mine, Bai Shi Du, Chen Xhou, Yizhang County, Hunan Prov., China.   This is an attractive crystal of bournonite with coatings of muscovite.  It is a high quality, aesthetic floater with some crystal regrowth on the backside.  It is always rare to find these specimens free of damage so this alone makes the piece desirable.  Minor base contact.  Deeply striated, highest luster, and nice complexities makes this a fine display specimen.  3.1 x 2.2 x 2 cm.  They don’t get much more attractive than this.  $280
