A cabinet specimen of purple fluorite on siderite from new production at the Yido Silver Mine.  To the untrained eye, this looks like a typical Yaogangxian specimen, but a slightly closer look reveals that the matrix is in fact siderite (rather than muscovite.)

I was offered a small group of specimens prior to Tucson which I declined due to the exorbitant prices, though I was happy to see one small lot available in Tucson as well. 

There is one bit of damage, this is best visible in the image directly below the description on the second-farthest crystal to the right.

Pieces like this are exciting because they come from a location that had previously not produced specimens. The bulk of the currently available Inner Mongolian pieces come from only 3 or 4 mine clusters ( mainly Huanggang, Rongguan and Chaobuleng)-- over 200 such mines and mine clusters have been opened over the past several years.  That pieces like this make it to the market means that there is a chance that a greater portion of those 200+ locations will eventually start to produce collectible specimens.

Sawn on the reverse.
