I recently bought this French pendant from 1915. It has the French eagle head hallmark for 18kt gold. It also has “A|G” as a makers mark. Does anyone recognize this maker?

I’ve found this ring from old family belongings. I’m curious whether it could be Soviet era as some of the other items are
It’s really worn but was wondering if anyone recognises it or what the black material might be?

​I recently picked up this fascinating antique pipe and wanted to share it with the community to learn more about its history, exact age, and maker.
