Tiny reddish orange prismatic crystals with hexagonal terminations to about 0.75mm with colorless and tabular Baryte crystals. The Vanadinite is somewhat color zoned. The last few photos are that of the Baryte. This is an interesting specimen of dissolved Galena which created the vugs to which the crystals have formed. There is also a green micaceous mineral, which is much like Sericite.
