Bright green micro crystals of Chromian Grossular cover one end of a large cluster of Diopside crystals. This is the largest specimen of this material I have ever seen. The Diopside crystals are also large for the location and have a more flattened, blade like habit than is usual. Many of the Diopside crystals have sections of green indicating the inclusion of chromium. For many years, this material was incorrectly labeled as being Uvarovite. The specimen is in very good condition ; however, the Diopside crystals are not terminated on the back side of the specimen.
