Hey,

I recently ordered a diamond, but I'm a little worried because it was one of the cheaper ones among diamonds with similar specifications (4C's), and the pics also looked comparably darker too.

Will this have any problems from what you can tell? Performance? I'm not an expert, so I can't really tell by looking at the proportions in the GIA report.

Finally ,what should I be paying for a diamond like this?

Thanks a bunch!

Did you get an aset or idealscope image? Or can you get one? The crown is a bit high. The stone is a bit deep.
An aset or idealscope would tell if the stone is leaking or not.

Do you have any up-close pictures? They would also be helpful.

$18k??? Edit...actually seeing $18 - $20k

You can run it through the HCA tool to gain a little more info on it
 
Probably will have a little leakage with the crown angle that high. 35.5 would have been the max I'd go with the 40.6 pavilion angle. It's also a little deep at 62.8%.

For future reference, check here before buying!
 
Is this from JA? Can you provide us with the link? Any photp or video?
 
Here's the link to a hi-res photo:

Also, the diamond in this photo seems a little more dull or brown compared to others on James Allen within this range. Would this just be image quality or could the diamond actually turn out dull?

Unfortunately, I got it on James Allen and they didn't give me one.

I added a link above.

HCA tool is giving me very good across the board. Just to confirm, is the middle number (62.8 ) the depth %? It's a little different than calculating it manually from the measurements (4.95/ 7.90 = 62.66.

How much of a visual impact will this have? Would it be better get a different diamond, perhaps with lower clarity but smaller crown angle?
 
I ran it through the HCA and it came out with very good for light return, fire, scintillation, and spread. The parameters we recommend will come out with a score of excellent for light return, fire, and scintillation, and very good for spread.

For people who know nothing about diamonds and probably have never seen a great diamond, this one will probably look very good to them. For those of us who have seen top cut quality diamonds, we wouldn't buy this particular stone. It is not bad in the overall scheme of things, but there are better choices. You definitely don't need VVS clarity, as VS1 is extremely clean and usually VS2 is eyeclean, also. But it all depends on what's available. Since James Allen doesn't provide the GIA reports or the measurements on their site, the only way you can search for stones with an excellent HCA score is to use the Pricescope search:


Click Show Filters and be sure HCA is set to excellent. You can still include VVS2 in your search but go down to VS2. Check it out and see what's available and you can post any potential candidates here for us to comment on.

Darn, I wish I knew about this beforehand!

How does my original pick compare to these? I'd be going down in color from G to H, and going down 1 or 2 levels in clarity from vvs2 to vs1/vs2. Also, the second one seems to have big imperfections from the images.

Would the "excellent" HCA rating be worth it from an eyes-only perspective?

I don't like the inclusions on that H VS2. They would bother me.

The 1.9 H VS1 gets a 1.7 HCA score which is in the promising range. The scores are light return excellent, fire/scintillation/spread very good. So it's better than your original pick, but it doesn't have the three excellents. I think it's the 41 pavilion angle causing it to be slightly off. You'll usually get the best scores when the crown angle is 34-35 and the pavilion angle is 40.6-40.9. BUT, this one is better than the original. Are you open to looking somewhere besides JA?

JA is the preference atm because I already put my order in for an engagement ring, and I figure it'd be easy for them to swap out the diamond.

I think the original scored a 2 HCA score. Can you explain why the 1.7 is better? Here's the score I got using one of my freebies on the original rock:

Too bad. It could have been a good 36.5/40.6. But see the wonkiness and mushness between the 9 and 730 arrows shafts.

I already explained why. The original only gets very good on light return, fire, scintillation, and spread and likely has leakage. I believe it got a 2.3 overall score, but you have to look at the components and not just that number. The one that scored 1.7 got excellent for light return and the rest very good. So at least it has excellent light return.

The one I posted from B2C gets excellent on light return, fire, and scintillation. You can see that it has a beautiful cut just from the image and video. But I understand if it's too complicated to switch vendors.

What about this one - it has excellent on 3 of the HCA factors.

But it's got a dark spot in the middle. Will this be visible to the naked eye? Better than my original pick overall?

Yes, that one is a really nice one! That little inclusion is going to be sooo tiny in real life. It likely can't be seen at normal viewing distance. Some people are extremely picky on clarity and wouldn't want that, but I think it is very unlikely that it would be noticeable. If JA has to bring in the stone, make it absolutely clear that you want it examined by a gemologist to be sure it is 100% eyeclean before setting it. I think it's a good stone and better than the others at JA as long as they can verify that the inclusion cannot be seen with the eye.

Okay, just had a chat with JA. They said the original rock was better cut due to the arrows. They do look more uniform than the F VS2. Any comment on this?


Original G-VVS2:

HCA Score 2 - Very Goods across the board

New F-VS2

HCA Score 1.2 - All excellent except spread (very good)

You don’t really see arrows in every day viewing. You do see light return and fire and scintillation, which are all Excellent on the F-VS2. So, that is the one I would pick out of these options.
