Estimated age 1950's but could be earlier. Martelli has been in business since 1931 and they are manufacturers of silver rings and jewelry. Quality, well made ring, even though it's adjustable in size. It has a nice weight to it. There is black enamel work around the edge and an oval of onyx bezel set in the center with a rs set in the center.
Rhinestones surround the onyx.
There is a red rhinestone ring on the finger and a blue rhinestone bracelet. Shaped like a clover, but actually it's three circles connected. Hitch is matte brass. Top is white. In overall good condition.
