It means that the ring is made of 10 karat gold, and "FL" is the mark of the manufacturer.

10K indicates that the item is 41.7% gold, with the remainder being other metals (such as silver or nickel). While this reduces the cost of the piece, it also makes the jewelry stronger.

Check out makers who use "F". The identification would then depend on the style of the letter and any other marks around it.

Unlike trademarks that have been registered with the U.S. Patent Office or with another country's patent office, maker's marks are unregistered. If you are unfamiliar with the name or symbol, consult a guide to identify the maker.
