VERY GOOD. This antique French Platinum Diamond five stone ring is in very good condition. The Platinum band is robust and will make for perfect everyday wear. The piece has a slightly faded dog head hallmark, but it is still legible. The Diamonds are super bright, and sparkle beautifully, free from any chips or fleabites. There is very little wear to the ring, only one very subtle resize mark visible on the inside.
