It's giving me a HCA score of 3.9

Thanks very much!

Your question will be moved to the Lab Grown Diamond Forum, but I would avoid any stone that scores a 3.9.

That's a big no! It's cut steep and deep. I see you just joined so I'd recommend you read some information about cut proportions to help you find a great stone. This is my favorite article on this website and it was written recently by some very knowledgeable diamond people. https://www.pricescope.com/education/diamond-cut/diamond-proportions

I would avoid it because of the combo of a steep crown and pavillion.

Rhino cuts an amazing diamond:

Your Custom Cut Distinctive H&A Round Brilliant Lab Grown Diamond

Distinctive Gem offers what we know to be the rarest cut round brilliants in way of LG diamonds *bar none*. These diamonds are the result of testing diamonds under the most scrutinizing conditions of my over 3 decades as a research gemologist. What makes the Distinctive Hearts & Arrows...

But at least start your search with the parameters given. Rarecarat is a good place to search but honestly I’d recommend going through a vendor like Distinctive Gem, Diamonds by Lauren or even Good old Gold if this is a purchase like an engagement ring. Picking a diamond from a selection vetted by experience professionals is way less stressful than searching on your own

This is great advice - WolfCBI now, too!

I saw this elsewhere on Pricescope and it got me even more pumped for the new collaboration of Wolf and CBI!

Thanks for the help and suggestions everyone. Just wondering, why do they assess it as "ideal cut" if the cut is so poor. Does light performance not form part of their criteria?

 

[dasitmane]

I found this one with a HCA score of 1.0. Any thoughts on this?

The answer to your question is that it depends on the lab. I personally would look for a GCAL certificate when buying a LGD.

Many of us here consider cut to be the most important C when shopping for a diamond. I'd suggest you read this article to start educating yourself so you can be an informed buyer.

Diamond Proportions

The physics of light-behavior within a diamond are reliably consistent, which means proportions measurements can be useful.

Here's an example of a well proportioned lab grown available through Wolf/CBI.

It should be okay, but could be a bit better. The table is a little large, and it won't have as much fire.
