A monthly updated list of Cornish and Devon is now available, many new finds from obscure locations and several rare species have been added, we always send the very best available and many have been subject to our Raman testing.
What is a Micromount Specimen.
Basically one of natures minerals with crystals so small that they need some kind of magnification to view and appreciate them to their full potential.
Many of the rarer species simply do not grow any bigger but are spectacular when viewed under a microscope.
All of our specimens are tack mounted in to a 28mm square perky box and fully labeled and can now be checked using our own on site Raman technology.
With an ever increasing collection of new, rare and interesting micro specimens we decided to invest in our own custom built Raman 532 Spectrometer to be confident in our descriptions and identifications. and giving customer confidence in their purchase.
A photo of the Raman Spectrometer is given below for your interest.
The important stuff:
While most photo's are generic, we always pick the best available. Those marked with a
# and a code number are the ones you will receive.
There is now a £10.00 minimum order on micromount purchase's.
Postage prices UK. Any mix of items under £20.00 at Royal Mails cost price £3.90.
Any mix of specimens over £20.00 can be combined up to the 2Kg weight limit of Royal Mails tracked and signed for service at a cost of £ 4.50, it makes sense to take advantage and order several items at the same time. Remember these postage prices are at cost we do not profit or charge for packing materials which are recycled when ever possible.
The 532 Raman Spectrometer shown under it's calibration set up, the green laser is normally shielded and protective glasse's are worn during operation. This has proved invaluable with the recent identification of a local mineral which had been found and described as " yellow wavellite", in fact it has now shown to be wavellite on quartz, the yellow dusting which was giving it,s yellow colour has now been identified as ferrimolybdite.
