Hi there – thanks so much for all the helpful information on the site! I’m looking at lab grown diamonds, primarily from James Allen and Clean Origin. Can I get your advice on which of these two diamonds is the better value? Both fall within your ideal cut estimator tool.

I’ve noticed on some of the IGI reports that Crown Height – Angle is not included. Should I automatically exclude any diamonds where this information is not reported?
Hm, I’m not a fan of the inclusions in the 0.74 E SI1 and I think the 0.80 I VS1 is brown. I think the options below would have better clarity.

Round,0.72,F,SI1,Excellent,870,https://www.diamondscreener.com/ja/loose-diamonds/round-cut/0.72-carat-f-color-si1-clarity-ideal-cut-sku-7586409
Round,0.75,E,SI1,Excellent,1010,https://www.diamondscreener.com/ja/loose-diamonds/round-cut/0.75-carat-e-color-si1-clarity-ideal-cut-sku-7563882
I would pass on the 0.84 H SI1 because there’s no picture to evaluate the color or inclusions. I would also pass on the 0.87 G VS2 because it’s filled with clouds and you can see the strain lines – I think it has reduced transparency.
The 0.82 H VS1 is a brown H, but it might be OK. Not sure if it’s worth $400 to go up 0.07ct though. Is the H a 40% better diamond? Up to you.
I wouldn’t bust your budget on the 0.9 E VS1.
Thanks so much, really appreciate the help. I’m hoping to have at least a .75 carat, and have narrowed it down to the following – of the below, do you still think the .75 JA diamond is my best bet, or do any of the others stand out?
