Description

Remarkable specimen hosting a thick carpet of jamesonite needles, nested on top of a pyrite and sphalerite drusy. Jamesonite is well crystallised, with its typical lustre. Among the crystals, shiny and well formed individuals of jet black sphalerite and golden pyrite appear, donatign a great aesthetic to the specimen. The matrix is grey-white quartz, whose vugs host some jamesonite needles as well.
In excellent conditions, this is a specimen dated back to the 70s. We have acquired it recently from a Swiss collection assembled a few decades ago. Pretty scarce material on the market.
