As the title says I would like to propose to my boyfriend. I want to do it when we go to Japan for the first time and I've talked to his friend over there about how to do it and for the most part I have everything figured out. Almost.

I know that its very unusual for females to propose to males so I'm at a lost for what kind of ring to get him. We both have promise rings and I gave him a stainless steel ring and for this one I want to give him silver for sure. But I'm at a loss in regards to what exactly I want to give him. Any advice in this matter would be very helpful and I would love to see pictures for inspiration if possible.

Thank you!
