An excellent cabinet sized sample of Japan law twinned quartz from the Fengjiashan Mine. Although operated since the 1950's, the mine's heyday as far as specimens are concerned was in the early 2000's, when it became famous for its inesites. These Japan law twins were another item of particular note, though I don't see good ones too often.
This piece has three main twins, aesthetically stacked on a quartz plate.
The piece is also sprinkled with many small, brown crystals of hubeite, a rare silicate discovered at this mine in 2000 and only found there .
