I have seen a fair amount of this huebnerite, it is not really uncommon as the find was quite prolific, but this piece is really good. None of the quartz crystals are broken, and some show pretty good transparency. The huebnerite is also not etched-- many of the huebnerites from this find suffered from excessive etching. Others were very thin and got damaged during extraction and transportation, and still others had the huebenrites jumbled together too closely. This one has none of those problems. This locality has produced some of the world"s best huebnerite; for the size range this is about as good as it gets.
