This is one fancy ring. Not hallmarked, but tested for sterling silver. The ring looks like a crown. There are pink natural Garnets and marcasites. Fancy design on the shoulders, and even the band has scrolls with much design. The top measures 1 1/4" X 3/4". Weight is 6.6 grams. Ring size is 8 1/2. I wouldn't re-size this ring. If you want to do this the band will be changed. Condition is good for age. The large Garnet has a chip at the top, and there are 2 marcasites missing on the shoulders. I would date this amazing ring at c1920's.
