Aesthetically perched on matrix are two, tabular, lustrous and translucent, rich sky blue alkali-rich beryl crystals, to 2.6 cm across. The crystals intersect each other at angles which enhance their display. One of the few elegant, display-quality matrix pieces in the pocket. These were originally thought to be Rosterite or Vorobyevite, but further analysis by Dr. Federico Pezzotta confirmed they are alkali-rich beryls.
