SV3140EJK: Rhodochrosite with Quartz
A peculiar discovery from 2021 in the Austria Duvas Mine, where these rhodochrosites appeared in rosette shapes associated with Quartz and minor Sphalerite. Their striking resemblance to the rhodochrosites from Cavnic, Romania, is curious to the extent that at mineral shows, Romanian dealers seeking pieces for their home market sometimes get confused and believe that they are from their own country. In any case, they are truly pretty.

EAP47AN8: Rhodochrosite with Quartz
Coralloidal growths of very lustrous rhombohedral Rhodochrosite microcrystals with an intense and uniform pink color, on matrix, with small Quartz crystals.
