Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
A blocky, black colored crystal of Ferberite. Two of the faces are striated One of the other faces and the termination face are flat. The specimen has a good submetallic luster.
Flaws: There is an area along the more acute edge of the termination which is not compelte. However, even with 10x I cannot determine if it is chipped or a contact area.
