This is a nice hand made Mid Century Modern sterling silver shadow box ring with gold metal center in a US 9.5 ring size. The inside of the band is marked 925 for silver content. I have not tested the metal content of the gold metal square inset within the ring face, so can only call it gold colored metal. The ring face is square with rounded corners. It has a square of gold metal centered inside of a border of darker patina.
The ring weighs 7.5 gr. The ring face measures .625" square. The band is almost 4mm wide.
Condition is good.
If you like the mod streamlined look of Mid Century Modern design, and also appreciate hand craftsmanship, then this ring may suit you. It would be fine for either man or woman to wear.
