rinstone or not this is not worth this price,
first of all there only about 1 carat of stones, and it doesnt even describe the quality of them, so basicly you can get the crapiest stones for way too much.
second of all, there nowhere described the weight of the ring, so you dunno how much gold there is in this ring, so basicly you could get a 1 gram ring, which could be way to much for it...
and for the amount of stones, its realy not work that price in every single way possible
