I have a strainer and 6 cups that test silver - hoping to locate origin - cups marker Silver Jadegreen. Strainer marked silver and 1 hallmark in a rectangle. Can anyone help? http://i.imgur.com/eTgjUjss.jpg http://i.imgur.com/DNtzByts.jpg http://i.imgur.com/590yWKvs.jpg http://i.imgur.com/SUf7gKLs.j...
