Can you name the mineral and where it comes from?

Mark did this a some of the club meetings. Let’s try it online!


  1. Mark Stanley says:

    It looks like Kyanite on Quartz from Brazil

  2. Ulli says:

    A wild guess
    Tourmaline (Indicolite)???

    • Donald M. Doell says:

      Tourmaline is correct. Elbaite to be specific. The variety is Cuprian Rich or Paraiba, although technically this one comes from a neighbouring province to Paraiba; the Province of Perelhas. The very small ammount of copper is enough to cause intense colour, usually blue, sometimes purple and green also.
