Cornish and British Minerals

I have been field collecting  Cornish minerals for over fifty years with several breaks while bringing up a growing family and starting my engineering business. It is not my aim to become a fully fledged mineral dealer as there are many other things in life to occupy my time as you will see on this site.

 

I have been lucky enough to acquire several very old collections over the years, some of the specimens from which are of no interest to me but are never the less of very high quality, some dating back to the 19th century.

A solid arsenopyrite matrix with crystals to  12mm, a really special piece from the late Donald Jenkin collection of Penzance and previously in the James Wickett collection. A small 50mm specimen but  in perfect condition.
