The display surfaces of this specimen are completely covered with dark, minty green, translucent to opaque fluorite crystals. Individual crystals reach 4.3 cm along the cube edge. Although this specimen doesn't have the deep minty color prized from this locality, it does have a rich coverage of fluorites with intense, bright blue fluorescence under longwave UV (second photo). (Same color but less intense under shortwave UV.) The longwave fluorescence is so intense that some blue coloration can even be seen outdoors on an overcast day. Except for the usual edge issue, no real damage is seen. The bottom is sawn flat (the silicified limestone matrix rock is very tough and a diamond chainsaw must often be used to extra specimens without damage), which provides a great display base without needing a stand.
