Two transparent Quartz crystals, with a slight frosting on some prism faces, have settled between them a large (35mm x 30mm) and translucent Apatite crystal. The light to dark blue graduating Apatite crystal also has a ghost imprint one side indicating the presence of an earlier Quartz crystal. Apatites of this colour and size are now very rare from Panasqueira. Well proportioned - choice!
