Two Vintage Avon 80s Purple Gold Green Silver Emerald Cut Rings

Two very pretty vintage 70s or 80s rings from Avon Ladies. One is gold style with purple emerald cut, the other is silver style with green emerald cut The green ring has a missing silver piece on one side, hard to notice I’m not sure of the sizes but I believe the silver ring is a 6 and the gold ring is a 5. I’m normally a 6 on my ring finger and the silver fits well there.
