VANADINITE ON BARITE

Bright red vanadinite on top of bladed barite, all on a large host rock. Many of the barite blades are coated with growths of a black mineral, which I'd assume to be goethite though I can't say for sure. Keep in mind that the standing position we put the piece in for photography isn't super stable; the bottom could be trimmed relatively easily given the softness of the barite.
