Geological and Mineral Slice's.

 

This page is dedicated to the growing selection of polished slice's and cut sections we are producing,  some of which will be offered for sale,  much of the material is brought to us by geologists, mineralogists and sometimes by the general public who have come across an interesting rock in their travels. The cutting and polishing on the correct plane allows the normally hidden minerals within to become easily visible.

We also take on small one off commissions, sometimes a mixture of polished minerals and cast tin. The candlesticks in the header picture are such a project, all materials were sourced from within a mile of our home in  Luxulyan
