Item Description

This remote Chinese locality has become a prolific producer of fine quality crystallized specimens. This beautiful cabinet display specimen hosts a pronounced, sharp, well-formed, blocky, soft greenish-yellow colored, doubly-terminated Scheelite crystal measuring 3.6 cm long with a few superb quality, very gemmy, colorless, octahedral Fluorite crystals measuring up to 2.8 cm across sitting on a matrix coated with micro beige-brown colored Nelenite. There is a thin unidentified "wedge"-shaped crystal on the specimen that measures 4.6 cm long, and I believe it is possibly Titanite based upon the habit, and the fact that a crystal this size has to be a fairly common species. Titanite is reported from the Huanggang Mine, but I can't remember seeing one prior to this. With that said, the crystal has not be analyzed, so this is merely speculation. There is also a pink fluorescence on this crystal, which seems odd for the species Overall, the piece is in superb condition, as I cannot find any major damage anywhere. A wonderful and showy example of this soon to be classic material from this unique locality. Priced at $6,500 in the inventory. Ex Dr. Stephen Smale Collection.
