Description
This beautiful thumber features two intergrown, multicoloured-blue clusters of rare blue Alkali-Beryl. They are well developed, sharp edged and showing a fine silky luster. The trasnparency is good and the overall aesthetics great. These were originally thought to be Rosterite or Vorobyevite, but further analysis by Dr. Federico Pezzotta confirmed they are alkali-rich Beryls.
