Bournonite with Siderite - Herodsfoot Mine, Cornwall

Bournonite with Siderite -
Herodsfoot Mine, Lanreath, Cornwall
38 x 35 x 40mm
 
A nice combination specimen of quartz with biscuit coloured rhombs of Siderite forming a sphere -like aggregate amongst which steely grey Bournonite sits.
Most of the Bournonite, for which Herodsfoot is world renowned, is massive with the occasional hint of a classic 'cogwheel' crystal shape.
 
An excellent representative species specimen for the locality at an affordable price for the Cornish Collector.
