This is a beautiful nickel Wine Goblet Kiddush Cup, with a small matching saucer that goes underneath it.
Both the cup and the rim of the saucer are embellished with lovely filigree work and a series of small blue crystal stones inset into the design.
There is a clear plastic insert for the cup, preventing the wine from interacting with the metal, which would cause the cup to stain and the wine to taste metallic.
