Description

I have handled a number of smithsonite specimens from this locality over the last few years but this is only the second one I have come across that has identifiable crystals. Small but highly unusual even for this rarely seen locality. 

A great example of very rare yellow cadmium smithsonite from probably the best smithsonite locality in the British Isles. The waste tips at the locality have now been bulldozed down the mine shaft, So no new material will be appearing on the market.
