Hey @jkallmeyer, you do this with equipment you have at home? That definitely is of interest since most of the technical equipment for cutting and polishing hard rock is quite expensive and also easy to ruin if you don’t know the proper handling. I have cut and polished hundreds of agate and fossil ammonites for museum events in Germany as give away. It is not as easy as it seams even with the right equipment. So once again, yes we are very interested in your setup and technique.
