Round Brilliant spec questions

[pickydiamondlover]

Hi Everyone!
Hoping someone can shed some light/opinion on the following... I know you really have to see the stone to know, but what do you think about a 3.00 Round Brilliant that is an Excellent cut, I color, SI2 that is eye-clean and does not look yellow? Anyone able to think of a reason why this stone hasn't sold in the last 2 years making it still available? It looks great, but I'm worried I'm missing something...you know?
It has a 2007 grading date-why might that be?
Thanks in advance everyone!

Can you attached the report here? Or at least give the GIA report number and exact carat weight?

 

[pickydiamondlover]

I don''t have the report #-BF has all of that
I just know the details-and wanted to help him figure out if it''s a good purchase...
Anyone have an opinion?

 

[stone-cold11]

Well, the GIA report will give the proportion of the stone and we can guess how good the stone is cut. Not all Ex cut stone are great.

Regarding why the stone might not be sold, could be just that it is worth too much $$? Not a lot of people has the disposable cash to buy a 3carat stone. Maybe it is a trade in stone, second hand stone too. Get it appraised by an independent appraiser if you are worried would be the safest way to go.

Okay, I found out the depth! 61.2% table 60%
symmetry is very good too and no flouresence.
Any opinions now?

We still need more information which is contained in the grading report for the stone.
A lot goes into a diamond in determining its value/worth, how well it perfoms.... A LOT MORE than a maul sales associate may know or tell you.

The best suggestion you can get right now is to begin reading the knowlege and education sections of this site. Don''t buy anything until you know the answers to the questions you have. Don''t take a sales clerks word for it, don''t take our word for it. This is a big purchase that warrents a bit of research. The good news is you found Pricescope before making a purchase. With a little reading each day you will be helping others to select diamonds before you know it!!!

60% table will have a slightly different look. Can you post the crown and pavilion angles and also the star and lower girdle facet numbers?

It could be fine but the critical factors are the crown and pavilion angles, if you could get that info that will tell us more. There could be various reasons on speculation why it has not sold, I would advise with a purchase of this magnitude to get an independant appraiser involved.

Table size is fine, some prefer the slightly larger tabled look, however in the non PS world a 60% table is not considered particularly large.

Thanks everyone again-I do appreciate the information-I don''t know where else I would go! BF is dealing with a diamond company - a friend of someone he knows I think... so not a sales clerk per se...nevertheless I am not quick to trust as it is!
I asked him to email me the other specs you suggested and here they are:
I''ve actually now seen the stone in person... I found it quite beautiful and white despite it''s I color...nor did I see any inclusions with the naked eye...
my concern would be if I got it outside or next to a diamond of a better color, it would all of a sudden appear more yellow...
Any thoughts-hopefully my new and latest specs below can help further determine the quality of this stone.
thanks again!


pav angle-41.2%
pav depth-43.5%

star length 55%
lower half 70%

lower half 70%
girdle med-slight thick 4.0%
cutlet-none
polish/sym both VG

table 60% - I thought this was on the big side? please further explain...I wanted a big table because i thought the stone would appear bigger??

depth 61.2%

crown angle 34%
crown height 13.5%

the stone is actually 3.02
has GIA cert.-don''t know the price, but could this be too good to be true?

Well its a big stone so it might show a bit more warmth compared to one of a higher colour anyway. It has good numbers and is what is termed a ' nice make' for cut, however the lower halves are comparitively short, personally I would prefer this measurement to be 75% or above but not much we can tell without an Idealscope image. If you are unsure of the colour, maybe going smaller with a higher colour might be the best way to proceed, especially if the thought of the colour grade is what we call a ' mind clean' issue...

I would try to look at some other large diamonds of similar colour and lab grade ( GIA or AGS graded) to see where your preferences lie for colour.

If you want to proceed with this diamond, definitely make the sale final on the diamond checking out to your satisfaction with an independant appraisal, but if the thought of an I colour is worrying you, just think about maybe going smaller and higher colour before you pull the trigger, if the thought of an I colour bothers you it might always do it, so think carefully before you commit.

Also it is important to know what are the grade making inclusions noted on the grading report? If they are clouds which are added on the clarity plot then make sure these aren't impacting brilliance, definitely get an appraiser to check if so. If it says " clouds not shown" in the comments section that is nothing to worry about, if it says " clarity grade is based on clouds which are not shown' this could be, or if you see clouds drawn on the diamond diagram. If you could check and report back that would help.

Not the best cut stone around, but for that size, no easy to find an ideal cut proportion.

 

[pickydiamondlover]

Thanks again for your honest opinions-this is a big purchase obviously...
The key says cloud, crystal, feather, needle, natural
comments say:additional clouds are not shown.

I know that sounds like a lot, but I looked at it naked and with a loupe and was not bothered by much, and I can be very picky and detail oriented!!!!
what do you make of those inclusion notes?

Also, I will have to do my own further research... (I''ve done a lot) but what do you mean by the lower halves are comp. short...what is the impact of that measurement?
Also from your perspective, is this a stone that seems to appear it''s weight, or might it appear smaller/bigger given it''s proportions?

Lastly, how does one get a stone appraised without buying it first? In layman''s terms, do you just ask the Jeweler to "borrow" it!?

Would the jeweler be offended if I asked if this was a used or traded in stone due to it''s 2007 date?

Stone-cold, when you say not the best cut around, please elaborate if you don''t mind...I plugged everything into that facet test on the GIA site, and it came back with "excellent" cut...

 

[stone-cold11]

GIA Ex cut allows for proportion that leaks light, this is bordering on that. With a larger lower half, it could be compensated but I think the lower half of this stone is on the low side, closer to 80% would have been better.

What is the dimension of this stone? From the numbers, it look like it will be near ideal diameter, which is about 9.35mm.

Check if the vendor is willing to send the stone to an appraiser of your employment. Independent appraisers are middle man in this case. He will check out the stone for you but hold the stone for the vendor. The stone is not yours while there until the payment goes through to the vendor.

 

[pickydiamondlover]

I see-thanks again-will the vendor be "offended" by that request to send to appraiser or is it common practice?
Thanks again-
measurements 9.25 - 9.3 x 5.68 mm
SOrry-I had that info too-didn''t think to include it.

 

[stone-cold11]

Should be common practice especially since it is such a big purchase.
