Wulfenite, (on Dioptase)


Mineral: Wulfenite, Dioptase
Chemistry: PbMoO4
Size: 55 mm
Owner: Crystal Classics
Photographer: Crystal Classics

A group of well-formed, dark green dioptase crystals (to c. 25 mm) is supplanted by bright orange-yellow crystals of wulfenite, the largest of which displays a thick, tabular habit and is c. 10 mm across.

Note that the wulfenite is, in turn, frosted by tiny crystals of late-forming dioptase (see Photograph 2;  FOV = c. 30 mm.)
