I purchased a pair of "Brighton" earrings on eBay. I know nothing about Brighton jewelry but...

am trying to learn. I did some research and see that true Brighton jewelry should have a "b'" in a heart as a signature. These earrings do not have a "b" in a heart, but they have the Brighton swirls on the back. Are all Brighton earrings signed with the "b" in a heart? Is it possible that because some earrings are so small they are not marked with the "b"?
