Thank you for your inquiry. I am happy to help!

The only one I would remove is the 3.01ct diamond. The proportions/ angles aren’t great.

Out of the three that are left, are you leaning more towards one over the other? Have you seen any of them in person?

Hello! Your info on diamonds is so helpful!! I need your help with 2 diamonds. Could you please tell me which of these 2 diamonds below will have a better light performance?

The 1st diamond is certified by AGS. If I decide to go for the diamond that is certified by AGS, does this mean that my stone will sell for more of a discount when I upgrade it compared to the exact same stone graded by GIA?

Hello again! The below diamond from White Flash will definitely have better light performance.

3.128 ct J VS2 A CUT ABOVE® Hearts and Arrows Diamond

Thank you for your reply. No, I haven’t seen any of the 3 remaining in person. The only thing that scares me is the AGS certificate. I have heard that AGS has lenient grading for color. Any thoughts?

Also it appears that this diamond below might not be eye-clean. Looking forward to hearing from you!

You do not need to be the least bit concerned about the grading standards for AGS. And the diamond is eye-clean. 🙂

Hi Sebastian,

What do you think of this diamond?

It is another great diamond. Truth be told, you have all the information you need on the White Flash website to make an educated decision.

The Idealscope image is perfect, which means it will have tremendous sparkle!

Hi Sebastian,

I received the following email from my contact Becca at Whiteflash and below is her analysis of the 2 stones that I have shortlisted. Do you think I should pass on both of them based on her feedback or do you think it’s safe for me to buy the one she is recommending?

I really can’t trust her advice so reaching out to you to get unbiased opinion. I trust your inputs 🙂

Thank you so much in advance!!

Thanks for calling me back just a bit ago. I’ve taken a look at the diamonds we’re now down to for you:

Whiteflash Diamond Comparison

They are both gorgeous but again my heart is over the moon with the 3.128ct. =) I snapped a few images on my hand and did a little video for you in regular day light balanced office lighting.

The 3.128ct is on the left closest to my palm and the 3.228ct is on the right. The 3.128ct’s crystals in the table area are mainly light in color with a small amount of black.


These are nothing I could see from 10 inches since it’s an eye clean diamond and looking at 6 inches I could pick up on it faintly when I knew just where to look and rocked the diamond back and forth slowly. Nothing I’d ever say is super obvious or could be noticed under a more casual inspection.

The 3.228ct had a few dark crystals under the crown facets and while I couldn’t see them at 10 inches it was easier for me to see these at 6 inches without much issue.

If I’m being super critical on these I also think the 3.128ct is the better J color of the two. Meaning more of a true J and not borderline color range. Please take a look and let me know what you think.

When it comes to the designers we spoke about here are the links to the their sites:





These have lovely halo designs that we don’t list on our site so if you see anything that catches your eye then please just let me know. I look forward to hearing what you and your husband think!

Actually, since Becca at Whiteflash has the two diamonds in her hands, I do think she has the advantage over the two of us.

I would go with what she suggests. I am confident you will be happy.  🙂

Got it! One question please – I want to maximize the diameter of the stone i.e I want the biggest size stone :))

She recommends the smaller carat diamond which is 3.126 – Carat and the measurements are: 9.39 x 9.42 x 5.76 mm.

The other stone that I shortlisted also from Whiteflash is a 3.228 – Carat and its measurements are: 9.42 x 9.46 x 5.87 mm.

Strictly, in terms of size, do you think I will be able to tell the difference between the 2 stones even if they are side by side or is the size difference going to be invisible?

Thank you soo much for all your help!!!!! You’re the BEST. Looking forward to hearing from you!

Your Diamond Teacher |

You will not be able to tell the difference in size. They will look the same. 🙂
