      This is just a rough piece that I thought someone would like since it has a both pink morganite beryl and light green aquamarine beryl in the same specimen. It is unique. Both parts are a little gemmy. Collected in 1945 by Hampson.

      Bright gemmy green prismatic crystals of emerald. The largest crystal (second photo) is the best and largest at 7mm. The rest are scattered and not as complete but show good crystal faces. Striking in person as the photos do not do it justice - the green is much better in-hand. The largest Pyrite crystal is 1.5cm.
