COMMENTS: This tourmaline came from a parcel of rough from the Oyo mines in Nigeria that I purchased about 15 years ago. Some of these stones have tested positive for copper content, so there is a good chance this is a cuprian or Paraiba type tourmaline, though this one has not been tested, so I'm not going to outright claim that it is cuprian...only a "maybe".
