Jewellery tools.

This small barrel is for polishing small pieces of jewellery. It’s contains thousands of ball bearings and detergent, placing the jewellery pieces inside and fitting the lid it’s placed on rollers which revolve the barrel. The ball bearings rub against the jewellery, burnishing the surface producing a very brilliant finish. My students would lynch me if I didn’t have this in the class, some students regularly bring all their jewellery to polish
