JFD197AP4: Calcite variety is not lacking in the Moscona Mine. Among so many, there is always one that for one reason or another attracts more attention. Such is the case with this piece, in which the darker-colored growth figures seem to want to show the trigonal symmetry that characterizes the species. Unusual and curious.
