Sterling (?) Silver Dice Earrings

Even if craps isn’t your game, these dice earrings would be perfect for a Vegas trip. These are very small and could also be used as a nose ring. They’re stamped, but the stamp is not very visible and their backs are stamped 925. I don’t want to guarantee them to be sterling, but I’m fairly certain they are. At the time I bought these, I wouldn’t wear anything but sterling silver. They’re priced accordingly, as if they weren’t sterling.
