I purchased this pretty vintage ring several years ago at an estate sale in Indiana! It is marked 10K and it was described as rose gold when I purchased. It is size 6 ½ and, based on the shape, it would appear to be a young man’s or boy’s ring. The cameo could be shell but I’m not certain. It’s a very stylish ring with lots of attention to detail and is in super condition. It has a small 1/32” split on shank that is not detrimental in any way.
