Hubnerite (exceptional, largest from Yaoganxian!) on Quartz with Helvite
Yaogangxian Tungsten Mine, Yizhang County
Hunan, 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 Yaoganxian in 1998. It seems these are also the largest Hubnerite crystals known from China, at 9.4 CM! Ferberite (the analog) is famous from Yaoganxian, 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 parrellel growth with full terminations. A dusting of micro Helvites (not confirmed) add a color contrast. Remarkably this specimen has no noticable damage on the delicate Hubnerite crystals. For any comprehensive Chinese collection or a Yaoganxian suite, this is something really special!
