Lustrous crystalsare all over this pretty specimen (not quite as red in person as the pics show) - measuring up to about 0.7 cm, so not large, but this piece is about the richness and profusion of crystals rather than single big ones. The crystals are on Baryte, with a black coated layer underneath the vanadinites providing contrast for the crystals. 7.6 x 6.6 x 6.6cm
