Hubnerite (exceptional, largest from Yaogangxian!) on Quartz with Helvite
stock #8.1-098
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
12 x 9.5 CM (cabinet)
price: $3600


An important Chinese specimen and a rarity, this Hubnerite is from the one time small find at Yaogangxian in 1998. It seems these are also the largest Hubnerite crystals known from China, at 9.4 CM! Ferberite (the analog) is famous from Yaogangxian, it has produced some of the worlds best. However, verified Hubnerite is only known in a few specimens. The crystals here are attractively perched on a long Quartz prism and this displays well from either side. The color is a lustrous black to a deep brownish-red. Strong lighting shows red translucence on thin edges of the crystals as is typical for Hubnerite. The crystals are complete, somewhat jagged showing parallel growth with full terminations. A dusting of micro Helvites (not confirmed) add a color contrast. Remarkably this specimen has no noticeable damage on the delicate Hubnerite crystals. For any comprehensive Chinese collection or a Yaogangxian suite, this is something really special!
