Actually, SV, Fancy Deep (and Fancy Dark) are past the peak on the "desirability" curve, which is normally somewhere in Fancy Vivid territory, so a very very saturated Deep (i.e. closer to a Dark) may actually cost less than a good Fancy

Two pearls of wisdom:

"All generalisations are false"
(anonymous)

"Epimenides the Cretan says all Cretans are liars. Since he is Cretan and knows the Cretans well, we should believe him"
(paraphrased from Paul's Epistle to Titus)

In that context (and in the context of someone who lately paid top dollars for a Fancy Deep - probably on a par with a good vivid, and is entirely happy with that), there is an interesting discussion on colour in Richard Wise's book on gems Secrets of the Gem Trade. I'll see if I can scan and post a copy of the relevant pages, but his argument basically runs along the lines of "people will pay most for what is most attractive" - for yellow and other light colours that means highly saturated and bright shades with a medium tone; for red (and pink), blue and green, medium saturation and medium-dark tone are more attractive, since higher saturation and darker tone become too dark for the stone's beauty and colour to be apparent in most lighting situations. Have you ever seen a really dark sapphire? It can look black - and it's a lot less nice than a medium blue!

[soapbox mode off]apologies for the long paragraph...

OMC- i tried to apply your self portrait here. It seemed appropriate. when you start talking like that, i picture you in your smoking jacket and glass of champagne  

YES! and 80% of the time, i actually understand it! 

I admit after reading that I went "duh"  It does make a lot of sense that it is that way.  I obviously knew that less color is desirable to a point and then there is the area where more color is more desirable too.  I sort of had that bell curve going on but didn't think that it would curve back at a point.

I totally get it all now 

I am on the fence about this one...  I am not really a fan of the heart shape (though it is pretty) but I do like the color...

I LOVE that orange. That heart really isn't my cup of tea. But price? If it's the right price it might be someone else's.

What r you talking about!
I think this heart is really lovely both shape and color. It will look amazing and really pop in single heart pendant. 
One of my concern is that it doesn't look very sparkle in the pictures. May be because the fluoresense. 

Namtan - I think the dark, saturated tone is why there isn't a lot of sparkle. A lot of light is absorbed by the diamond.

GIAGirl: normally the house and the baby come after the diamond. And the ring. And the dress. And the cake. And the trip. But perhaps I'm rubbing salt on open wounds here. 

i'm all about the sparkle. i would love to see both stones out in full sunlight, that way i could judge the sparkle factor.

That is interesting, I didn't realize they could be too saturated and reduce in value.  That orange appeals to me.   Stats? 

0.72 fancy deep orangy yellow; SI1; strong yellow fluor - R3114. Currently being set.

That's the one. I'm coming to NYC to pick it up in early April - if any other CDIers are in town, let me know and we can meet!
