Description
 
Wheal Bungay, St. Agnes, Cornwall.

A fine specimen displaying feldspar crystals to 12mm across replaced by black cassiterite in pale hard elvan matrix.

This specimen was collected when a tractor ploughing a field in March 2012 on the Wheal Bungay mining set which is situated next to wheal coates struck a mineralised elvan dyke and exposed several fine specimens. This example has been cut and polished to reveal the replacements more clearly.

Size 8 x 7 x 6 cm
