Hi Denise, in the early part of the 20th c, the Keystone Publishing Company published an annual guide called The Jeweler's Index that contained marks and other reference material. The maker's mark (below) was from the 1922 edition. The A inside the form of a bell in your pink gold ring which you ask about, may be the maker's mark - Abel Bros. & Co., Inc., New York - it would also coincide with the date.

Denise we really do need to see a close up photo of the marks. You can add a photo in a follow-up submission.
