AGI on jewelry refers to the Accredited Gemological Institute, and when it appears on a piece of jewelry, it means that it is what it claims to be. The AGI has accredited it as such. If it is on a piece with a diamond, the diamond is genuine.
In the U.S., solid gold jewelry is marked with the purity and the hallmark (trademark) of the maker. So, for example, my wedding ring is marked 14K FG which means it is 14 karat gold, made by Frederick Goldman, Inc.The maker's hallmark can usually be found by searching the US Patent and Trademark Office's trademark database (but the search will probably be tedious).here is, however, an exception, and that is that GF is the standard abbreviation for gold filled which means it is a cheaper metal core coated with gold on the outside. In other words, it is not solid gold.
