Magnificent group of stacked Cuprite octahedrons, the largest of which is .7cm on edge. The luster is a beautiful brushed metallic silver, and the modified edges of the crystals add even more drama to the piece. Naturally, there is some contacting along the back, but it is insignificant. When you see how fantastic these Cuprites look as they glow red with transmitted light, you can appreciate even more what a first-rate specimen this is.
