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.
After thinning down my collection I will shortly be disposing of a quantity of mineral cabinets with a good provenance. There will eventually be eight modular unit,s, each 27" high, 20" wide and 24" deep.
Each one holds seven slide out drawers and a large top drawer about 5 " deep. All have 1" thick teak tops which once served as working desk tops. All need a little tlc but all in sound condition.
Many of you may have actually used these if you trained at CSM
No minerals included.
I would prefer to see them go to local mineral collectors so if of any interest please make contact.
They can be sold as single individual units , units of two, a unit of three and one desk unit and will start to be available in about three weeks time, from July 20th 2024 onwards.
Viewing possible before that time by appointment.
Priced at £ 60.00 each upon collection.
