“A unusually large single twinned cube of glassy blue green fluorite with purple centre zone and lighter purple edge zone. Crystal has some natural etching at base and on one face - also one one edge. Nevertheless it is a great piece.Blue Circle or Eastgate quarry is due to close this year. It is also understood that the outcrop of this fluorite has now been buried.”
