3.1 vs 3.6 jump in price per carat

[Acrata]

I think it's reasonable to expect a higher price per carat for a 3.6 than a 3.1, but can anyone help me determine if this jump is in line with how much the overall market charges for that size increase?

3.106: https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3809557.htm
$33950, or $10930/ct

3.656: https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3855505.htm
$46507, or $12720/ct

(Both ACA I SI1)

I met with an appraiser who said the 3.656 is above rap price. I don't know if that means it's overpriced.

Which is more in line with the market?

Pricing depends on lots of factors - particularly how much diamond prices were when each was acquired by WF. A 3.65 has jumped that 3.50 mark and they do grow much more expensive as the size increases - particularly in large stones. I would call Whiteflash and ask them about the price difference as I am sure they would be happy to discuss some elements of it with you. They both appear sold though; did you purchase one or both of them?

I just googled a rapaport price list and it lists prices from 3-3.99 so rap price there's no jump. However market price I'm sure the 3.65 would be priced closer to a 4 carat on a price per carat basis.

Ugh, that's a stupid thing imo for whomever you met with at the Gemological Appraisal Laboratory of America to say to a retail shopper -- especially when s/he leaves it in a vacuum, doesn't follow up with an explanation of what "Rap" [Rapaport Price List] is & why it's nigh meaningless for us consumers (I'd say "totally meaningless," but imagine there are Trade members here who would say, and explain why, that's too absolutist).

Real quickly, 'cause I'm leaving soon for JFK:
* The Rapaport Price List isn't a compilation of the prices paid by consumers. Nor are the numbers (couched as price/carat) "the wholesale price" (there is no such critter) for the diamonds in each of its categories. Its prices also are not the mean or median ones actually paid by those in the trade in the preceding week. It's the high, asking B2B cash price; used to be the high, asking cash price in the NYC market, but I'm not certain if it's still limited to that.
* The Rap List doesn't account for all factors to be considered in the pricing of stones.

P.S. You could use the PS Diamond Search function to see per carat, retail prices for all PS sponsors' diamonds (in-house & virtual inventories) . But the tables of results won't be (and honestly, cannot be) as specifically concrete for comparison shopping purposes as what I think you're hoping for. Here's a screen shot of the results of my search there for round, I diamonds of SI clarity between 3.56 - 3.70; you'll see that even within that narrow field, the per carat spread is more than $3500. You have to dive behind the face of the results table and, e.g., view the lab reports -- PS does make it easy to do that -- in order to suss out those which are truly most comparable.

More simply: do you all think one or the other is a much better value? Let's suppose the cut, color, clarity are identical within their grades.

GAL didn't opine on whether the rap price mattered. Didn't say it was a rip off or anything. In particular, I was already aware that rap missed a lot of factors.

Whiteflash said the price per carat difference was because one is over 3.5 carats. No other reason given.

Thanks all.

Also: I ran out of time and didn't compare these two against each other side by side in a variety of light environments. Is it fair to assume they are cut equally well because they are both ACA?
