Hi Sara thanks for writing in. It sounds like it might be Bates and Bacon, jewelry manufacturers of the US. Could you confirm for me if there is a shield or not a shield around the letters and if you can see a decimal point after each letter B - you might need a jewelers loupe or magnifying glass as it being an antique gold bracelet, the marks might have worn away.
