50mm Moon Stamping Blank £0.65 These are 50mm aluminium moons. 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. These moons are great for pendants as celestial jewellery is very popular at the moment. Try mixing them with our star blanks on long chains or cords.
