Bournonite

ID: CC19021
An excellent small miniature of well crystallised Bournonite intergrown with both drusy and sub-mm Quartz crystals.  From Herodsfoot mine, world famous for its very fine Bournonite, this specimen is rich in steely blue-grey cog-wheel Bournonite crystals, with many measuring to about 1 cm across.  A great and well-priced example of what the miners termed “cog-wheel ore”, now known to be a lead-copper-antimony sulphosalt.
