Love / What would be a traditional wedding ring for a man? [6]

I am an English woman and have been with my Polish partner for over a decade. We are getting married this year and as we're both older and on second marriages it's a relatively informal occasion. But I'd love to buy him a ring as a surprise. That said, I can't find any useful information on traditional rings for Polish men online (possibly because I'm googling in English!) There's of course articles about wearing rings on the right not left hand, but any attempt to find 'Polish wedding rings for men' just returns results for the more common translation of 'polish' in this context - i.e. it's been shined in a particular way!

Neither of us are expecting to spend a fortune because at this stage in life it's the fact of marriage, not the spectacle of the wedding. I've seen some really lovely rings, in titanium, silver, and even steel. But before I buy one, can anyone advise if there's a traditional style, or metal or anything else, that a Polish man's wedding ring would usually be expected to have?

Any advice would be great please!
