I watched this guy's videos: http://www.youtube.com/user/jonmervis/videos?view=0 http://www.youtube.com/user/jonmervis/videos?view=0 I also learned a few things while shopping: 1. You need to see the diamond in person. 2. Size is easily quantifiable, but sparkle/pop is more important. See #1. 3. I don't like to haggle. So I went to a diamond wholesaler, which was basically an office environment as opposed to a sales floor. I took my time, didn't feel pressured and I walked away with a great diamond at a great price. I can't recommend this option enough. 4. Not all certifications are equal. If the price seems to good to be true, it probably is. This is especially relevant for online vendors. Another random tip: before you propose, secretly make a manicure appointment for your significant other for later that day or the next day.
