Vintage Old Pawn Red Coral Turquoise Floral Ring

Vintage old pawn handmade ring set with small turquoise and red coral in a floral design. There is one part on the ring which I showed in the last picture that I'm pretty sure it's part of the design but it could be a missing stone. I think it's just the design as the bezels on the other stones have a "jagged" edge and this is smooth, so I think it's just a fancy loop. There is stubborn hard to remove tarnish. Size 5.75 Stamped J, S, and P. Ring is not stamped but does acid test positive for sterling silver. G
