Vintage MMA Sterling Silver Ancient Urn Reproduction Pendant

this is a cool little sterling silver pendant made by MMA museum of metropolitan Art. It is used and has some wear and tarnish. I have seen another that was gold washed. I'm not sure if this one used to have goldwash and it came off or if it's Sterling variant. There is a gold tone in some lights. It is tarnished but nice shape. It's pretty heavy for a pendant and weighs approximately 10.8 g. measures 1 1/4" x 7/8"
