Hi,
I an not an expert, but was interested in a piece of jewelry that had a hallmark of 220 and was being presented as 22k gold. Ran a number of searches on the internet for 220. So far, the only information that I have been able to come up with is that 220 is used to identify commercial bronze which is an alloy of copper. A web search on "alloy 220" will bring up a number of sources on the subject. Good Luck.
What else can I help you with?
What does 220 mean on a gold hallmark?
220 is not a gold hallmark. The lowest number that is used as a gold hallmark is 333 (meaning 33.3% gold content, which is 8 carat, the lowest gold carat). 220 is actually the hallmark for bronze, which is a copper alloy called "Alloy 220" (or sometimes sold as "commercial bronze"), not gold.
