What is this line going through my diamond?

[GG0809]

Hello,

I am newly engaged and my fiancé bought me this lab diamond from Brilliant Earth. I love my ring, but I keep noticing this faint line going through the diamond.

Can anyone tell me what this is and how it affects the diamond? The ring will sometimes appear dull in certain lighting and I am curious if that line is the cause of this.

Here are the specs below and some pictures of my ring in different lighting. Any information on what this may be would be greatly appreciated!

1.52 carats
I color
VS2
Ideal Cut
Table: 56.5%
Crown height: 15% - 35
Pavilion Depth: 43% - 40.7
Total Depth 61.7%

I believe it is part of the growth matrix (Stria) since it is lab grown. Let me see if I can find you a link.

Maybe this explains it: you probably have CVD grown lab diamond

We don’t recommend brilliant earth. If you choose to return it, I don’t expect you will have an easy time.

Btw, congratulations on your engagement and the ring is gorgeous despite anything you might notice. No one else is going to scrutinize the ring like you will. It’s a nice size too!

Wow thank you for that article and your response! It is a CVD diamond and that explains so much!

Also, you may want to get an ultrasonic cleaner from amazon.... I have the magnasonic. Diamonds get filthy fast.

When I was first here I was like “why is my beautiful asscher suddenly grey and not performing well...” FF buying a Loupe on eBay and getting a magnasonic and boy was it filthy! I mean it was layered in dirt and oil.

So it could also be looking diffused because it needs a good cleaning.

I will definitely be purchasing one ASAP. I have noticed that the diamond gets very dirty, very fast. So I know for the future, who do you recommend when purchasing lab diamonds?

I don’t really know, other than I think I would prefer hpht diamonds.

I recently bought a tennis bracelet from James Allen that is really great, but it’s only 2 ctw so the diamonds are small.

I also have MMD around my yellow sapphire ring that David Klass sourced when he made it. I don’t know anything about them other than they are beautiful.

Your ER is a knock out
Just ignore that little line
or think about it like the growth rings on a mighty oak tree

It might be girdle reflection. You can use the search function and find a plethora of pictures from other PSers on the topic.

That’s a girdle reflection; round brilliant diamonds have them, mined or lab.

To me it looks like the line across the bottom is the girdle reflection. I don't know what the darker slightly angled line above that is. Maybe stria but I don't personally know much about that.

+1 for Girdle reflection (presuming you're looking at the light line running roughly 10 to 4 on the clock)
