Many professional rock enthusiasts keep a dedicated barrel on hand to complete the final stage of polishing because it can be very difficult to make sure that no grit is left behind in your barrel when switching between shaping and polishing steps in the tumbling process. By having an extra barrel, you don't have to worry about rougher grit scuffing up your gemstones while you are trying to get that finished polish.
