Nice looking sterling silver band ring. Siam Niello, stamped Siam, Sterling. Suit men's signet ring, or a unisex casual ring. Great design, with a figure of a water carrier. I have a Siam Niello Elephant brooch in another listing too. The band is not in quite a perfect circle, more like an oval, it comfortably fits size R to S. I measure it as R and a half. Size 8.5 to 9 in USA sizes.
