I’ve never been particularly enamored with my monogram. The one exception would be signet rings. Old or new, I think they’re so stylish.
If you want to customize your ring, you need to buy a blank like this one that can be engraved to suit your taste. If you want something less expensive, any jewelry store from the mall to 5th Avenue sells blank rings for engraving.
Antique signet rings can be found on Etsy, eBay, at antique shops or in Grandma Millie’s jewelry box. I especially love rings, like this one, that look aged.
