Description : what does the stamp 705 on a ring mean?
Last Answer : The 705 stamp equates to 17 karat gold. Gold is stamped based on purity, with 24 kt gold being pure gold. 18kt gold is stamped 750 because it is 75% pure. 17kt gold is actually about 70.8% pure, ... as 18kt or 14kt, but it is available. Especially in parts of Europe, Asia, and the Middle East.
