I have a few chains from my aunt's estate that say "24kt GB" on their tags that are part of the links to identify the amount of gold in the chain. I can't find anything that describes the "GB" mark other than it might be a country mark which could mean Great Britain maybe? It's very definitely "GB" and not "GF". Is anyone familiar with this mark?
