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.
Minerals Also Purchased.
The time has now come for me to specialise in one area of my mineral collecting hobby with the focus on minerals from the Mid Cornwall and I will always purchase good quality specimens from this area especially those from the clay country.
