The hoop or pendant is VERY OLD. I believe that the necklace is a little newer.
Signed 925 on both the necklace and pendant. Teh necklace is marked "ITALY". Both have initial marks. STERLING SILVER AND MARCASITE PENDANT. BEAUTIFUL AS SEEN IN PICTURES.
18 TOTAL LENGTH. The hoop is 1 1/4" in diameter.
The pendant is missing a couple marcasite gems.
