NEW  RUBY/SAPPHIRE  MINE  IN  WINZA/MPWAPWA

  
       Werner Radl,  MAWINGU GEMS ( http://www.euromineral.fr) sent an email describing the reopening of this mine.  Pictures of extensive pitting, fine faceted rubies, and an interesting ruby/sapphire dogtooth point make this an interesting revelation.  We will have more to say about it after Werner returns from field explorations in June, 2008.  Here are some images of the workings, and a couple of stones from the locality.  
 

         
 

 
  

Perhaps the best known material from Tanzania is the red and green ruby in zoisite from "Longido".  Several areas produce gem rubies and sapphires, among them "Morogoro",  "Songea",  "Tunduru", and "Umba".    "Ketito" is regarded for its elongated pink ruby crystals.
