Do they make engagement rings for men?

An "engagement ring" can be any ring that the person chooses to wear. It need not be sold as an "engagement ring" or made of a specific metal/gemstone or look a certain way.

If your boyfriend wants to wear an engagement ring, then get whatever he wants. If you want to present him with a ring when you propose, then go to a jewelry shop and browse. Ask the clerk for help if you wish.

Or talk to him about the engagement (which you should do anyway, regardless of who is proposing) and then the subject of rings can come up naturally.

Or propose without a ring, then suggest that you guys pick it out together after he accepts your proposal.

Yes. It fits in his nose.

recommendation: solid white gold, simple but 'strong' (manly) design...

good luck ;)

Yes. They are all over the place. Or you can have one custom made.

Any place that sells men's rings...

Any ring can be an engagement or wedding ring, that also applies to women.

Engagement rings are just 'rings'. Any ring that you want to propose with can be an engagement ring.

There are a lot of them on Etsy.

Ask him first- if he's uncomfortable wearing one, you've put your future husband in a very awkward position.

My son n law had one. It was a silver möbius ring.

If you ask a jeweler, he’s bound to have ideas! And if your man wears rings, I don’t see why you shouldn’t buy him a ring with a diamond in it. In my opinion it would look comical worn next to his wedding band. It’s more usual to buy one’s fiancé a different sort of gift, such as a watch, cuff links, pocket knife, or a money clip or pen. All those things come in precious metals.

ANY ring can be an engagement ring as long as it is given with the intent to marry the person wearing it.

So yeah, they make lots of engagement rings for men.
