I think the other two stones scored about the same. 3 isn''t terrible, but it''s not top of the line either. It''s the crown angle again.

Well this is I think the 5th Tiffany stone posted here that has a 35.5 crown angle and 40.9-41.0 pavillion angle. Which makes me wonder if this is coincidental or if Tiffany prefers diamonds with these angles?

I don't know the answer to that question.

Are these GIA Excellent/AGS 0 stones? If not, maybe ask for those.

Again, in my opinion, ok, so Tiffany's is your thing, I get that, but I don't get paying double and only getting an ok cut. I'd want the best cut. So maybe ask for more of a range of color and clarity and tell them that you are only interested in AGS 0 stones? Yes, Tiffany's stones are better than average, but when you can get an ideal cut for much less somewhere else, you're not getting what you paid for with a 35.5 crown angle and 40.9 pavilion angle, IMO.

Howdy. Whew guys. We had better BE CAREFUL before we begin criticizing Tiffany's. That is surely a quick way to lose the respect of..well, the entire world's population in regards to our understanding of diamond cuts!

At leat your average person.

I will join in even though I might not be the most reliable source of information (though I have gotten better now! I was able to very easily detect the color face up in some very well cut H color diamonds today--albeit I began the observations by comparing them to my E.)

However, We all know what the HCA says, and we should also know that there are supposedly many wonderful beautiful cut combinations not recognized by the HCA. frther, since we know those HCA scores I suggest we put our collective minds together to figure out exactly why tiffany's likes this combination together. Here our my thoughts:

The first thing that speaks out to me is the 80%LGF with 50% stars. My understanding is that this should create numerous pinpoint flashes of color as opposed to broader flashes with shorter LGF--but, as I said, they should be more numerous.

Then the crown angle, I understand, continues that phenomenon, making it even more exagerating. As we know, the FIC is supposed to consist of a higher crown angle along with other traits that yields less white light return but more pinpoints of fire. But that would benerally be higher crown angles right? Thus the crown angle here, it seems to me, COULD be a great balance between white light return and emphasizing those pinpoints of fire een more than the LGF already does.
Thus again, NUMEROUS pinpoints of fire over broader burst of fire.

But many people find broader burst of fire more attractive--my self being one--and so perhaps

The slightly higher pav. angle combined with the higher crown angle is reducing white light return JUST ENOUGHso that it reveals and emphasis the fire and makes it seem slightly broader than it woudl with "optimum" white light return--but not so much of a loss of rwhite light return as to make it look dark.

Thus my inexpericned analysis of the cut based on the assumption that Tiffany knows what it is doing as well as the HCA does, is that the cut that tiffany is using is designed to create more burst of fire and slightly reduce white light return so as to make the colors clearer and broader. Resulting in a fireball of a diamond that has more and clearly visible (translated to the eye as broad) flash of fire?

Maybe I am crazy, but before I start criticing Tif. I am going to have to assume they know whatare doing! Hopefully somebody will come and pick apart my theories, as obviously with only 3-4 months of private studying I really don't know much. But I am mostly just trying to get the ball rolling rather than get the final answer.

Otherwise, I really don't understand why you are trying to pay for a diamond now instead of waiting until you can go and view them...as I still don't see anything about this diamodn that really makes it special? unless the price is just wowing you...

Thank you guys so much for all the comments. No more Tiffany posts from me anymore I promise (will decide either to go for it or find something else this weekend).

Workinghard your answer is quite technical for me not sure I understand everything you said, but I think i get the picture. By the way you were asking for Tiffany Japan''s prices earlier, I dug out the information hope it''s what you are looking for:

From Tokyo, pretax prices (5%), using 1$ = 120 yen
0.9 carat, F/VVS2: $16,178, 1.25 Carat/F/VS1: $23,725, 1.33 F/VS1: $25,133.

I calculated for the same 1.25 F/VS1, Japan is about 5,000 more. My friend had told me that Japan has an almost 30% premium but I didn''t believe her. Seems that she''s right
