Thanks for the insight. Here is a link to the diamond in the pictures: http://www.brilliantearth.com/rings/cyorings/view_diamond/2563514/?sid=girlguineapig|1474925711|4081010 said:This diamond isn't even close to true H&A. But H&A photos don't necessarily tell us anything about light return. Can you get us the pavilion angle, crown angle, depth %, and table % for this stone? Also let us know your budget and what range of stats you're looking for.
Here a few nice diamonds. But let us know your specifications and we can help you more.
Thanks for sharing your insight! The first one seems pretty good, even though the crown angle is 35.5. Seems like the 35.5/40.6 combo scores well on the HCA but 35/41 doesn't. The second one has 'strong florescence' which combined with E color is apparently a bad combination and can make the diamond look hazy.girlguineapig|1475001591|4081331 said:Hmmm. That one is pretty deep. I am not an expert so am not sure what I would recommend out of the few Canadian diamonds available.
Both of these ones from Russia have good numbers and the first one has a really nice photo:
Since this is an upgrade, maybe you can ask them to notify you when something matching your criteria with the following numbers comes up?
Depth % 60-62.0 (up to 62.2 may be okay)
Table % 53-58 (53-57 may be a little safer)
Crown Angle 34-35
Pavilion Angle 40.6-41 (some prefer 40.6-40.9)
Let us know your thoughts. Hopefully someone else can advise you on the best of the Canadian diamonds available at Brilliant Earth.
The angles on this one are not complimentary. As the crown angle goes up, the pavilion angle should come down. So a crown angle of 35 or 35.5 will work better with a pavilion angle of 40.6. A pavilion angle of 41 goes better with a shallower crown angle of 33.5 or 34.arjunrattan|1475070713|4081615 said:I found this one that seems to have slightly better proportions. I have requested images to verify.
Thanks for those suggestions. I did see those ones but both have 'internal graining' and/or surface graining. Is that something to be concerned with? I noticed a post on here where a user noticed internal graining lines on a VVS Clarity diamond.ac117|1475072575|4081621 said:The angles on this one are not complimentary.

These two are both only $20 over your budget but fit the rest of your criteria and have very nice, safe numbers. I took a look through the rest of their inventory and a lot of their stones don't have complimentary angles:
