About $1200 back in 2010. Got a nice enough ring she'd feel proud to show it to people, but didn't pay any more money than I'd saved up since I decided to propose.

To keep costs down I got a 'perfect' diamond with an occlusion you couldn't see without a jewelers loop, and had sapphires on the ring to add interest without increasing the size of the diamond.

I'm happy with the decision still 15 years later.
