A great "toenail" specimen of the sought after yellow sphalerite on lollingite combination.  The sphalerite is complete and damage free, and has good color.

These yellow sphalerites remain among the most sought after items from the mine, and are among the most scarce-- I saw fewer than 4 of these sphalerites in Tucson, and this price is considerably better than anything I saw at the show.

The sphalerite/ lollingite combinations are particularly rare-- most of these sphalerites occur with calcite, and quality of the sphalerites on the sphalerite/ lollingite combos is typically lacking...though that is not the case on this piece.
