Sterling Silver & Pearl Long Necklace

Gorgeous necklace! I thought it was sterling but could not find any markings and tested one of the balls as well as the chain and yes it’s definitely silver. Then when cleaning a ball I found a tiny small 925 stamp on a ball bead- there’s only 1 as far as I found on this 40” necklace. Necklace is closed no clasp. Genuine pearls through out. I wish I knew the maker because it’s truly a beautiful piece, but sadly I do not. Total weight is 40 grams. In great condition!
