According to a show I recently watched, a good wedding proposal requires the following : a great setting, the perfect ring (Well...this one is only required by the ladies. Haha. Just kidding.) , and of course the right person. I definitely agree on the last part, and as long as it's the right person it will always be a great setting no matter where it is or how the proposal was planned. But if you are going to ask me, a good engagement ring would be something like or close to cubic zirconia rings, a simple elegant cut always seals the deal.
