An awesome looking Clear Quartz Elestial or Skeletal formation, aka Crocodile or Alligator Quartz.
The faces on Elestial Quartz will grow from the edges to the center. Sometimes these faces simply grow as thin transparent plates, then usually several generations of them can be found, separated by empty spaces. Should these plates finally be completed, the water inside will be trapped. Elestial growth is indicative of an unrest geological environment with rapidly falling temperatures and/or pressures.
