List of MMD / Laboratory Grown Diamond sellers

If you can find some great options to pick from that aren't poor crystal material (the leftovers that the upper and middle tier sellers rejected), then go for it.

How can I pick better choices? There so many 4 carat to choose from? What proportion to look for?

Another very popular online forum has a lot of people with positive experiences with Luvansh and Calavera. Calaveras prices look suuuper juicy https://calaveranewyork.com

How to pick a good one. The diamond is from Calavera. So many to choose from the list. Need help finding the best cut. Can I tell light leakage with dark shades on the diamond vidoes?

It's not a matter of strictly proportions and angles, color grade, and clarity grade...it's also the quality of the diamond crystal. A diamond with perfect proportions that was cut from poor material is still a nicely cut diamond with poor material.
Think of it as the undisclosed 5th C: Crystal Quality.
Even if it's a nasty grainy CVD or color hued HPHT, most labs (including GIA) aren't going to say anything about that poor material quality 99.9% of the time.

So can I look at images and videos on the diamonds and see any dark area would be light leakage ?
