1.36ct intense blue

P.S. Because buyer premiums are so much higher nowadays than the commission that sellers pay, here's Christie's current schedule of buyer's premiums (Sotheby's is the same; Bonhams' is structured somewhat differently):

On a "hammer price" of $1 million dollars, the top bidder will pay an additional $195,000. Assuming that she is charged a 10% seller's commission (plus ancillary fees for photograph & shipping, if it's sent to another location), she will net much more than $500,000. Even if the hypothetical buyer wants the "all in" price to be $1 million, meaning a hammer price of just about $840,000, she'd still net more appreciably more.

It would be very interesting and informative for us to hear what the auction house(s) think is the appropriate price range estimate & what she learned about their private sales program for jewelry-gems, if she explores that in her discussions.

As a very rare fancy blue diamond there aren’t many buyers out there, though any of them will have plenty of money if the diamond appeals to them.
it really needs to go to a premier gemstone and jewellery auction, the ones held by Sotheby’s or Christie’s in HongKong or similar. These auctions attract the very wealthy and top jewellery houses looking to create an “ultra piece” and to some buyers there is an ego boost to winning the bid on a rare and desirable gemstone.
its not in the sort of price range of “ordinary folk”. So it’s not going to find a buyer is a “retail” situation.

this is what I have asked about as well and she doesnt reply on it. I can understand that the trade need a big mark up as they have to sit on the inventory until someone buys and when you go past these shops they are never busy.

$1,640,000 was the winning bid here in NYC last month on a Tiffany solitaire ring with a 3.02 ct cut-corner square modified brilliant diamond that GIA graded as Fancy Intense Blue, VS2. So more than twice the weight of the stone the OP has asked about, but not IF in clarity.

Because the price shown has all those zeros, I'm guessing it's the "hammer price," doesn't include the buyer's premium.

I'd like to correct myself:
The auction sale prices that Phillips reports do include the buyer's premium. Phillips' sliding scale is (as of September 1, 2019) is 25% on up to the first $400,000 of the hammer price; 20% of the hammer price between $400,000.01 - $4 million; 13.5% of the hammer price that's higher than $4 million. So the hammer price for that much larger FIB, one of Tiffany's "Stones of Distinction," was just shy of $1.4 million.

P.S. I looked again today and am still not seeing any meaningful FIB comparables, with actual price reported for a sale within the past several years. Sorry.

There are not that many such things.

only matching the GIA color grade and allowing some leeway of weight, thre are a couple of references, updating & other refinements require extrapolation.
