Until I researched it I would never have thought vanadinite likely to occur at Ilfeld in Harz, Germany.
The specimen we discovered is a manganite matrix with tiny pockets of braunite, and with one solitary yellow (part) crystal within.
Being solitary and measuring c.5mm we can hardly call the specimen rich, but certainly rare!
Checking out references online the picture you can see is one of only two photos online, the other you can see via the Mineralienatlas link below.
