Here is a great Deco ring with marcasites and crysoprase, a semi precious stone typical of that era. It is a 2 step ring with pave set marcasites framing the green rectangular stone. All stones are intact and accounted for and undamaged. It measures 1" long, 1/2" wide and is approximately 1/4" in height. The ring is size 7. There are no hallmarks on the ring but test sterling.
