37mm Aluminium Moon Blank £0.59 These are 37mm aluminium moon stamping blanks. They are cut by hand from 1.2mm thick/16 gauge aluminium so are nice and thick to stamp on and get a good impression. As they are cut by hand the sizes and shapes do vary slightly. Aluminium is a great alternative to sterling silver as it does not tarnish, is light weight and you can polish it up to give a lovely shine. This size is perfect for pendants, celestial jewellery is very popular at the moment. These moons look great also hanging from a choker or memory wire.
