This is a REALLY unique Yaogangxian fluorite specimen. On a large plate sparkling with glittery purple fluorite microcrystals are three large crystals (to 1.8 cm) that grew, then were coated on some faces with a white mineral and others with purple fluorite microcrystals, then later began to grow again in a TEAL-BLUE color after the solution in the pocket had changed -- creating these amazingly and pretty phantoms! 12.9 x 11.1 x 4.1cm
