Hi, diamond professionals, what do you think of this diamond according to both IGI and GIA:

1.08 ct, round.
measurement: 6.61 - 6.65 - 4.00 mm
polish/symmetry: excellent/excellent
VS2
color: I
Fluroscent: fainte
cutlet: none
girdle : medium to slight thick

table: 60.4%
depth: 62.7%

crown angle: 36
pavillion angle: 41



Is it worth buying in terms of cut (light return, fire, brilliance)?

Also shall i be concern about faint fluroscent for the diamond? Somewhere from googling, i read that a slight fluroscent is actually good for color "I" and it makes the diamond a little whiter, yet it won't make diamond look milky. Is it correct?

I'm confused--this diamond has certifications by TWO labs? or you're asking us to judge something that someone is asserting to be that, based on GIA standards. I'm confused...

[LaurieH]

And you are correct on the fluorescence. And considering it's "faint", it's not something that is going to affect the appearance of the diamond, one way or another. You really only have to concern yourself at all with florescence in a stone when it's medium or higher, as it won't have any impact on the diamond--good, bad or otherwise.

CYANG,

Probably a very nice diamond. Looking online, there is one that is for sale on [url="http://www.bluenile.com"]www.bluenile.com[/url] without any fluorescence and the price is $5,656, and that price is confirmed as a good price -- on [url="http://www.diamondpricebluebook.com"]www.diamondpricebluebook.com[/url] the blue book price for that diamond is $5,740. With fluorescence, the blue book price drops only to $5,685. If you can get the one you are looking at for a similar price and you like the diamond, go for it. Best of Luck. Michelle.

It doesn't really have the best of numbers. Do you have a price on it? Do you have a photo of the stone or video of it?

It is GIA certified. I think IGI is just appraisal. So the information is copied from GIA.

Any particular reasont hat it is said not having good number? What i care the most is whether it is a excellent cut by both GIA and HCA standard? I tried with HCA calculator, the score is pretty bad. Does that mean the diamond won't be sparkling? The whole point of diamond is supposed to be sparkling to me.

The price of the diamond including the platinum set is $5000.

Is the grading report (GIA) issued after January 2006? If so, there should be a cut grade (not symmetry, not polish - cut). If it does not, something is wrong. If the report is older than that, there is also something wrong: the dealer probably knows it's not a splendidly cut diamond, and is trying to get away with it.

Secondly - the HCA may well be irrelevant at this stage. It takes into account 4 average measurements (which are the same by which Jan is making her comment), not all the facets in the diamond. Chances are it doesn't look fabulous based on those 4 measurements - which is what Jan, the HCA (and I) are telling you. But it doesn't mean it's not a stone you may like or fairly priced.

Have you seen it? Do you like it? If so, ignore what the HCA tells you; it's built to express Garry Holloway's preferences, not yours.

On the other hand, if you haven't seen it and you trust Garry (the HCA), Jan and me, and you want a fantastically cut diamond, leave this stone alone.

a 36 degree crown angle is not eligible for a GIA 'excellent' cut. You don't have enough information to answer the question about light return, fire or brilliance.

You can play with their system online at www.facetware.gia.edu

What's the GIA report number?

It seems cyang has either bought this stone or another one...

If it is the diamond in your photo, I would say that from the photo, it looks to have a very deep pavilion and kind of a fish eye look to it. That is why the diamond appears very dark in your photo with sort of a white ring around the inside of the stone.
