Most of the charms say sterling either on the charm or on the circle part that connects to the bracelet. Didn't see a mark on the cups or cake. I tried reading the lords prayer in the bible couldn't really make it out. This was my moms charm bracelet and her dad wrote the dates of when they got the charms on the paper. Ask if you have any more questions. Roughly 75 grams can't weight it perfect cuz of the cardboard on the new ones.
