If after you smoke cleansed it, the feeling went you then I’d say you did a great job!
You can also use a soft toothbrush with a mild cleanser like Dawn dishsoap & rinse it thoroughly, then use the smoke again if you still feel it needs it.
My wedding rings were also antiques, and I saged them when they came home.
I didnt wear them often because of my job, but when i did, i would sometimes smoke cleanse them, just to get rid of any energies picked up out in the world. Also left them under the full moon a couple of times, not sure why (just washed them with the rest of my crystals and gems i guess?) or if it did anything.
