This is a dramatically large Mid Century Modern sterling silver pendant and 18 inch necklace chain. The pendant is marked sterling on the back. The necklace clasp is marked Sterling Mexico. I don't know if the pendant is original on this chain or not, though it is a good match, so I can't judge whether the pendant is from Mexico or not. I suspect not. The pendant is composed of 3 joined silver bars that have been flattened on each end.
The total weight is 33.6 gr. The necklace chain is 18" long. The pendant measures 3.5" x 2.5", excluding the bail ring.
Condition is good.
The pendant has a large bail ring making it easy to swap on and off the chain.
