One of the few attractive matrix pieces - Aesthetically perched on pearlescent muscovite is a cluster of tabular, lustrous and translucent, sky blue alkali-rich beryl crystals, to 1.4 cm across. These were originally thought to be Rosterite or Vorobyevite, but further analysis by Dr. Federico Pezzotta confirmed they are alkali-rich beryls.
