I’d be interested to know where he got them too. I have seen them before but I don’t remember where.
I have a friend who just lives down the road from me. He’s a really talented engraver. He actually made my wedding ring. One of the things he will make are rings with a family crest meant to be pressed into hot was to make a seal. Just like they did centuries ago.
If anyone is interested in that kind of thing he’s a really good guy. Has clients all over the world. If you’re on Instagram he’s @coasthandworks or his shop is here:
