Because it is a cluster, and large, this is a really good example of this rare replacement! Grossular garnet has completely replaced a former epidote crystal cluster (floater, with the largest crystal 7 cm and doubly-terminated). On the grossular, later-formed diopside crystals have grown. The whole thing was encased in, and dissolved out of, calcite by the collector (Ken Hollman). In good shape and complete all around except for two small damage spots at the top right and top-left of the large crystal's termination (or this would be twice the price, as well). Ex.
