My biggest worry about this diamond is the striation clearly present in the material. I know there tends to be differing opinions on how much this impacts the optics/if you need a pro to vet out the effect for you. Perhaps it'd be a negligible effect in this case, perhaps not.
Apart from that looks like a nice rock!

I agree that the material could be better.

Its not going to be eye visible except in just the right lighting and just the right angle and there are probably a couple dozen people in the world who would even look hard enough to notice or care at this level.
Diamond came and it’s far from a dud, but the fire seems less chunky (maybe muted is the right word) compared to my wife’s AGS stone (has the additional light performance grading and is rated a 0).
The wife doesn’t mind the more splintery fire and appreciates how it doesn’t go dark in certain circumstances. I’m happy as I can’t turn down a good deal and it was <$1k.
Will post a comparison video once we have it mounted. Below are the specs of the stone I’ve been comparing it to.

Does the LGD take on a bit of a hazy, cloudy, blurry, or subdued appearance in certain lighting conditions?

A 2.73ct for <$1k??? You scored!
Of course, you still want an excellent stone, but good deals make everything better in my mind. I once bought a car I didn’t really like bc it was such a great deal so I’m not the best voice in the room at the moment lol!
(Took it back 2 weeks later so all those “savings” went down the drain haha)
Can’t wait for the photos!

Does this stone look any better as it relates to the issue you are referring to?
Not sure if it matters to the human eye, but the scintillation map has way more activity….

I’m still seeing some striation. From my understanding most CVD diamonds will have it to some degree. HPHT won’t have any, but may have some color issues you have to be aware of. Doesn’t mean you have to go HPHT, many CVD diamonds are great!
The cut on this one isn’t nearly as good as the one you originally posted imho. The arrows are really skinny and the hearts image is far from the original diamond, which looked to have quite good symmetry.

In my opinion, I think this is an 8X that should have missed the 8X mark. The cut precision seems a little lacking.

HPHT can also show strain and graining. Here’s another thread where @Garry H (Cut Nut) explains a bit more.
Strain Lines
How common are they in CVD grown diamonds? I've noticed a few diamonds in my FB groups that look.. "off", kinda hazy and it's not the clarity. So I saved a pic of a 4ct that looked weird to me, zoomed in, and think I can see the strain lines. Not sure if it's OK to post the pic here though? So...

@Texas Leaguer also explains that strain and grain can happen in mined diamonds.
Do all CVD diamonds having straining - including “single growth” or “slow growth”?
I understand CVD’s have (or can have?) straining problems, and it seems obvious to spot on poor quality diamonds. But what isn’t clear (at least to me) is what a really good CVD looks like - should it have no straining or is a little bit considered normal / acceptable (ie negligible on...
