    I’d really need to see the inclusions to make a decision.

    The price is cheaper on the first because it’s smaller (even though it’s such a small amount) and the clarity is worse

    IMO, it takes more than colour and clarity to judge a stone. Cut is more important than either to me (within certain parameters, of course), and you mention nothing about cut here. Are both stones GIA or AGS graded? Do you at least have table/depth measurements?

    @ECH258:  What are the cuts of each diamond? Cut is the ‘c’ that has the biggest impact on sparkle, so i couldn’t say without knowing that. I would also want to see an inclusion map for the diamond that is an SI2 especially.

    I like what the .65 is doing with the light, G is a great color, and it’s less included!

    Unfortunately there’s so much more to diamonds than carat size, color and clarity. You’ll need to give a lot more info for us to give an informed opinion.

    The diamonds are excellent cut according to who? The jeweler, or an independent lab? If a lab, which one? There are major differences on how strict the various labs are. Even GIA has quite large parameters on what an excellent cut is (relative to AGS), so there are better and worse excellent cuts.

    I’m assuming you’re working with an online retailer, since they sent those photos. They are using a specific imaging method for those photos (the name escapes me) designed to show the inclusions. That picture doesn’t tell you anything about light performance (sparkle – the most important factor)

    Ask for an idealscope picture and compare it to this picture.

    Get the pavilion and crown angle, table and depth %, then plug them both into the HCA calculator. You’re looking for a score less than 2. Post the angles here if you want, or better yet, make a thread on Pricescope and the good people there can help you. Diamonds are more complicated than anybody first thinks. You’ll want experts to turn to. Best of luck!
