A large cabinet specimen of lollingite, examples of the species have been found here for approximately the last year. While the majority are typically plates of smaller crystals (sometimes very large plates), there are some sheaves of larger crystals available as well (see below)
This piece is about as good as they get for the location, and it should be noted that this find represents the best-of- species occurrence. Although larger pieces have been found, those are always plates composed of many sub-2 cm crystals-- on this piece the crystal sheaves reach 10 cm. Not only that, but the flower- like arrangement and overgrowth of bright arsenopyrite crystals give it a particularly aesthetic appearance, for a usually dull sulfide. In some areas, there is also a molybdenite coating that gives it a pleasing gun-metal color in some areas.
I learned long ago that when it comes to new finds of Chinese minerals, to get the best pieces possible as they are coming out, because they only get harder to find (and more expensive) later on. With that in mind, I jumped on this piece-- even if I end up keeping it for a while, it never hurts to have a top piece from a best-of-species find tucked away. Heck, the way prices are working with minerals from this site, in a year I"d probably have a hard time buying this myself... as an example, the asking prices for many specimens similar to those in my earlier Inner Mongolia updates are now higher than what I posted them for....
AND IT WEIGHS 10 POUNDS! Somehow I am always extra-impressed by rocks that are really, really dense.
