When I first saw this, I was a bit confused-- pretty much all the Chinese gibbsite I had seen was that blue hemimorphite-looking stuff, and it came from Yunnan Prov.  I was in Hunan, in the center of mining country, and these were even associated with (fluorite which was definitely local).

Perhaps most interesting however, are that there are actual CRYSTALS visible.  Gibbsite is almost always a botryoidal mass or coting, this piece has actually visible crystals sprinkled on a fluorite matrix.  The visual contrast between the color and form of the angular fluorite crystals and rounded gibbsite crystals makes for a very interesting appearance, in addition to the mineralogical oddity of the piece.
