Cuprite crystals to 1.9cm on a flat Chrysocolla covered matrix. These came out years ago and are among my favorite Cuprite specimens as the Chrysocolla really sets off the Cuprite crystals. Main crystal is sharp with just slight edge chipping in one area. There are also many more crystals present (can be seen along edges) that are completely covered by the Chrysocolla and could be exposed. Areas of fibrous Malachite crystals enhance the look.
