Rings
It is possible to say that since there have been men, there have been rings. Thus there are all types of old rings: simple ring or complicated work, mourning ring or promise of love, in gold, in simple metal, in hair or elephant hair, with secret or claim, the ring is a jewel that is easily worn and is shown in all environments, at all times. It is worn alone or combined with several, on one, two, three fingers. Sometimes even on each finger.
Men are not left out: old little finger rings like the signet ring, which was used to affix one's seal; bishop's rings, because yes: the ring can be religious. Memento Mori rings to remember the loved one, to contemplate the emptiness of his existence. As you will have understood, there are old rings for everyone.
It's up to you to find the one(s) that suits you best.
