UAT7 Quartz incl. Hedenergite with Hematite
Huanggang Mine, Hexigten Banner (Keshiketeng Co.), Ulanhad League (Chifeng Prefecture), Inner Mongolia Autonomous Region, China
One of the top examples from a find of hedenbergite included quartz made sometime in mid-2013. This piece is associated with hematite rosettes.
A number of pieces were made available by a wholesaler in Denver that year, but these were cherry picked by a (discerning) friend before the show, upon their arrival at the wholesaler’s warehouse. While the majority of what I saw in Denver were single crystals, many with chips or damaged terminations, the specimens here represent some of the best from the find.
More importantly, the arrangements are quite beautiful.
The crystals themselves are a very interesting color—their cores have segments that are are somewhere between a light smoky and amethystine, with a thick outer rind that is colored faintly green by what I assume are microscopic hedenbergite inclusions. The end result is this very unusual greenish quartz. Unlike many earlier finds, the surfaces on these pieces retain a high luster (not etched, as with most others) but still display the complex faces that care a characteristic of quartzes from this mine.
