Where Can you Purchase Rock Polishing Kits?

You can find polishing machines at a local rock shop, or from collectors, or you can buy it online if you don't mind the shipping costs. Finding a gem and mineral club near you would be the best idea; they will direct you to trustworthy local dealers and you'll find out if other collectors have any used equipment for sale. First figure out exactly what piece of equipment you want: a tumbler, cabochon machine, flat lap, or faceting machine.
