The pendant is 1 3/8" across with a 20" chain.  Both pieces are 18K gold over sterling silver.  A section of the chain has some tarnish.  This portion was not inside the plastic bag.  I have not tried to polish it.

This was among am aunt's things.  The receipt is dated 2019 with a price of $139.00.

I am helping older relatives downsize.  We have other items listed and are happy to combine shipping when possible.
