Lab Grown Diamond Help!

[abiquiuhoney]

Hi there! I would really love some advice on this diamond: https://certificate.diamondfoundry.com/download/243821.pdf

It's a lab grown diamond from Vrai/Diamond Foundry and I will like it in the three stone ring here: https://www.vrai.com/engagement-rin...t&ringSize=5&diamondLotId=243821&flow=setting

I know that J isn't great, but do all the other specs look good?

It’s a steep crown and a steep pavilion. Typically you want a shallower crown to compliment a deeper pavilion, a deeper crown with a shallower pavilion or something that falls right in the middle of both.
I’d still be curious to see pictures, but there should be plenty of lab diamonds available in the size you’re looking at, so if it doesn’t look stellar, you should continue your search.

Interesting. I guess I saw that those two (crown + pavilion) were in a good range... I attached an image of the diamond. It's very, very affordable (even for a LG diamond) of that size, so I was wondering what the issue with it was. I guess it's the crown/pavilion issue?

You can run the angles through the HCA tool to check how it scores.

(You only get a few (three?) free goes, though.)


re: the grading, this concerns me:




So not actually graded by a grading house and instead graded in-house?

Does the HCA tool do oval diamonds? I thought just round. And yeah, that in-house grading worries me... I just love the ethics and design of the e-rings and would love to buy from them. Sigh.

Also, I attached another PDF of a different diamond. Something I see a lot with oval diamonds on their site is a table diameter with a very small %. Could this be a typo? 4.15%

(I'm new to all this, so thanks for your input!)

A J from diamond Foundry will be have a Brown tint. They are using old machines. If you don’t want any of their speciality cuts I would stay away from them. Get a nice diamond somewhere else - look at it at home and see if you like it and then send it to a jeweler of your choosing for them to make your dream setting. Don’t have a diamond set yet into a non returnable setting without having seen the diamond (especially any color lower than F in lab diamonds).
