What does 725 stamped on a gold 1865 pocket watch mean?

It means that the gold components of that pocket watch are made of 18 karat gold. The max is 24 karat gold (pure gold). Most high end jewelry are made of 18 karat and very rarely 21 karat. There are no 24 karat as they would be at high risk since pure gold is very malleable (can bend easy). Since 18 karat and 21 karat are not 100% pure they are mixed with usually copper for yellow gold or silver if you have white gold.

What does 875 stamped mark on jewelry?

what does 875 on jewelry mean? actually i have never heard of 875 in jewelry,which when there is such a thing as a number in gold , 585 which means 14k,or 417 meaning 10k,or 750 meaning 18k etc,but never heard of 875..875 marked on gold jewelry would indicate 21 karat gold. It isn't that common, but sometimes seen.If marked on silver, it would indicate something a little less pure than sterling silver, which is .925 (meaning 92.5 % pure)So, in either case, .875 means 87.5 % pure.
