The one on the left weighs 17 grams and is about 40 mm across. The other weighs 7 grams and is about 35 mm across. There’s a half loop on the back for the chain. Both are hallmarked as sterling silver. This was a new departure for me. I created the two starfish shapes using a mouldable plastic called ‘Polymorph’ and these plastic models were used for delft clay casting. They are on sale in my shop.
