TM68G9: A very rare species, scarcely appearing in esthetic pieces. In this case there is a complete rosette of bicolored crystals of Wurtzite (some of them bright black and some other brown) and so well positioned on the Quartz matrix that it results in an attractive specimen. The group is completed by a curious Fluorapatite crystal, tabular and extra-flat.
