About this specimen

At arm’s length it looks as though someone has drawn spun metal over the rock. Move closer and the haze resolves into thousands of bismuthinite needles — silvery, hair-thin, some longer than a centimetre — lying matted and interwoven across a dark grey-black matrix. Small colourless quartz crystals push up through the felt in glassy knots, and pale carbonate crusts show along the lower edge where the needle cover thins out.

Bismuthinite is bismuth sulfide, Bi2S3, orthorhombic, and at Mohs 2 it is softer than a fingernail. In this acicular habit that softness is the whole story for a collector: the needles will bend or shear under a brush, a fingertip or a careless wrap, and they do not grow back. Display it under a dome or in a closed case, move it by the matrix, and never dust it.

The piece measures 9.1 × 4.3 × 6.4 cm and weighs 221 g, wedge-shaped and stable on its broad base. These photographs document the very specimen offered here.
