There are several excellent colorless mangangordonite crystals on this specimen. Two arrows point to the crystals. The upper points to a small cluster. The best crystals I could not capture, but near the top arrow are 2 or 3 very nice, sharp crystals. The lower arrow points to a good 1mm crystal. The crystals are just like those seen on Mindat. Very rare having been found in 4 or 5 localities worldwide.
