BLF01 Quartz incl. Hedenbergite
Huanggang Mine, Hexigten Banner (Keshiketeng Co.), Ulanhad League (Chifeng Prefecture), Inner Mongolia Autonomous Region, China
I very rarely purchase such large specimens, but occasionally I find one that interests me. More often than not, the disqualifying factor is simply damage-- the larger a piece is, the more chances that somewhere on the surface area of its display face, something will go wrong-- either naturally or during extraction. On this piece however, I only find a couple missing crystals near the edges-- it is as close to perfect as something this size can be, which is remarkable considering how many hundreds of crystals are on it.
The crystals themselves have a deep green color from hedenbergite inclusions, semi rounded terminations, and the complex lateral faces that is a characteristic Huanggang quartz-- these lateral faces reflect light nicely when the piece (or more easily, the light) is shifted-- it's not once of those etched, dull pieces-- the closeup gives a sense of this.
