Rich specimen of rare Uvarovite, the green chromium garnet. Uvarovite is very hard-to-obtain and never seen from this Californian localtiy. These are very limited in supply. Crystals are about 0.5mm and well-defined with many lustrous and sparkly faces. The purple is chromium clinochlore, kammererite. This is probably the better specimen of the three posted in this update.
