Incredibly intense green crystals to just over an inch, highlight this cabinet-sized dioptase. It is one of the most flashy, "electric"-colored examples of the species we have seen, perhaps due to some thin secondary growth that causes light to reflect a little different off the surface of the crystals. Normally material from this locality is very deep green, just without this super high luster effect. Although there is some peripheral damage, the display core of the piece is both intact and impressive. Lastly, the MAJOR CRYSTAL IS JUST A HAIR UNDER 3 CM ACROSS...HUGE FOR THE SPECIES!
