yes have to get one blue nile to get trade in credit. It ends up being more but I get to keep a stone for pendant I was going to trade in this way. So effectively I get more diamonds lol.
Thank you for advice. Will try to see if I can handle payments this way, paying both. :)
And have one from James Allen one from Blue Nile unless Blue Nile can somehow find that 2.13 and order it.

Gorgeous!!! So glad to see that! James Allen's prices are lower than BN, so I wouldn't allow them to call in the 2.13 unless they are matching the JA price.

Got it!
Blue Nile said they can maybe price match but not guaranteed. 2.13 is on hold with JA, so if Blue Nile wanted it to sell to me, if they matched price or were slightly higher, how would I handle that? Release from hold?

@diamondseeker2006

the diamonds came in and the Blue Nile one is in a mounting and James Allen j ordered loose. The Blue Nile 2.11 is not as sparkly as the JA 2.13. They both have excellent HCA scores (under 1 I think).

Do you think the angles are off on Blue Nile? JA has more light return and fire it seems. It’s just more sparkly. Need to figure out if to keep BN one or exchange. JA one is perfect.

BN forgot to polish inside of mounting so I wonder if that’s the reason.

Please help!

Good HCA score is 2 or lower. A score of 1 is not better than 1.9. Anything under 2.0 is worth considering. Usually you're going to find the best stones within 1-2.

The BN stone does not have the same angles as the JA stone. The BN stone looks beautiful in the photo, but I believe I said earlier that the JA stone had the best cut as far as numbers go. So I assume you are seeing a cut difference. It doesn't mean the BN stone is bad, but if you want the cut to match, you'll need to be looking numbers very close to the JA stone, which is 56 table, 34.5 crown angle, 40.8 pavilion angle, and depth close to 61.2.

Got it thank you so much.

Also do you recommend anyone to set my earrings since they are from different vendors? Many jewelers including HPD do not insure stones that aren’t theirs. So if you don’t have insurance and they get chipped or stolen, you’re out of luck. And for those who do have insurance on their stones I wonder if their insurance would have any exclusion if the Jeweler chipped them. I can only imagine if a person walks into a new jewelry store or moves and cannot go to their old jewelry store where they bought the diamond and something happens to it I don’t know that they would even know that the drill Jeweler did not have insurance

Let's find someone nearby to set them so you don't have to send them somewhere. Tell me the nearest large city where you could drop off the diamonds and we will see if there is a highly reputable vendor we could recommend to set them. It is always best if the diamond vendor sets them, but that definitely won't work in this case. I'd try to temporarily insure them through Jeweler's Mutual as they will insure loose stones as long as you can show the stone information and the setting information. Or at least they used to do that.

Also what is the perfect range for super ideal stones? Table 55-58? Crown angle 34.1-34.7? Pavilion 40.8? Depth 60-61.5? How would I know which stones is super ideal?

I think I listed the measurements needed above somewhere. Superideal cuts usually fall into T 55-57, D 62.0-62.3, CA 34.0-35.0, PA 40.6-40.8.

The stone that is closest to the first JA stone is this one:


Angles and diameter are close. Please note that most stones on JA and BN might not actually qualify as superideal cut if they were being sold at a superideal vendor. As in, they might not make the top ACA cut at Whiteflash, but they might fall into the second category of Expert Selection. We could tell more about cut if you ask them if they can provide ASET images, but the numbers suggest stones that should have excellent light performance, and they would be considered in the higher end of GIA Excellent cut.

Most crafted by infinity High Performance Diamonds are around 61.2 so under 62 for depth. And most are 40.8 pavilion. Same with white flash. I did not see any 40.6.

Is there a tighter criteria for super ideal? Not ideal but really super ideal?

I see I did make a typo up there. Should have said 60-62.3 for depth, but 60-62.0 would be my preference if I had the choice (and I do since mine are from Whiteflash).

Every vendor has their own parameters for "superideal". If you want superideal cut, you'll need to buy from Whiteflash or CBI. If you want ideal cut, then you can look within the parameters I gave you for GIA Excellent cut which allow just slightly more options. Whiteflash uses the parameters I gave you (Table up to 58 (most will fall 55-57), CA 34-35, PA 40.6-40.9) but do stop at 62.0 for depth. But you technically could go to 62.3 if you found the right pair assuming all the other numbers were right and still get top light return.

You will see 40.6 PA when a crown angle is 34.9-35. You might see a 40.9 PA when the CA is closer to 34. Most of the stones listed on the superideal vendor pages will fall in the mid range, though. The two stones you are looking at have the 34.5 CA, 40.8 PA and all good numbers and are an excellent match. I think it's as good as you can do without going with a superideal vendor.
