Advice for a young beginner please
About a year ago, my six year old son asked me how the opal on my necklace became so pretty so I showed him one of blackopaldirect's videos and he became absolutely fascinated with the fact that seemingly ugly rocks can be turned into something totally different. For half a year he used my nail polishing tool to polish bigger pieces of fluorite basically every morning. He's almost 7 now and has shown amazing dedication to this hobby so I'm trying to slowly improve his tools. He got a battery powered rotary tool and I tried to find some suited bits. I don't know a lot about lapidary but I'm trying to learn enough to support him. I made my own DOP-wax cause it's hard to find where we live and it works...ok I guess. Any hints on decent materials, web pages, stores (we live in Europe) what to look for, what to practice would be greatly appreciated.
