Pink drusy crystals of rhodochrosite coating acicular kutnohorite and white calcite that fluoresces red. 40x36x33mm.
Pink rhodochrosite with small white crystals (kutnohorite?). These white crystals are also included in the quartz. Ex Barry Johnson Collection. Video best viewed full screen.
A mixture of Mn-rich calcite-Ca-rich rhodochrosite pseudomorphing kutnohorite, sitting on drusy quartz crystals. According to Ralph Bottrill, analyses showed Mn40Ca60 and Mn75Ca25 from XRD. This specimen is quite pale compared to others found on a field trip...
A couple of very sharp analcime crystals nestled amongst pale pink kutnohorite from the Emilie Mine (Bülten-Adenstedt Mine), Peine, Lower Saxony, Germany. It’s nice to see zeolites in unusual combinations.
