SuperbCert vs HCA - help

[coblo]

I''m considering this H VS2 SuperbCert GIA cut & polish & symmetry Ex, but the hearts look a bit sketchy and the HCA is 3.5. Also there is an inclusion or something very clear in one arrow that is not shown on GIA report. Nothing against Excel, just looking for more opinions. On the otherhand the BScope is VH, VH, H and the arrows look real sharp. The price seems quite reasonable. Any opinions? Pics attached and in following posts.

Thanks,

The HCA score could be down to the steep pavillion angle, this diamond looks good! I would ask the vendor as to what that mark is on the image as he will be the best person to advise you. Being a VS clarity I wouldn't have thought it was an inclusion necessarily - however I could be wrong, but wouldn't want to speculate as the best person to help is the vendor who actually has the diamond.

From my own basic knowledge, it seems like it's a pretty good stone. It just seems to be leaking light around the table (see how it's a pinkish-red in the center). Because of that, you are probably getting a good price on the stone. However, if that makes you nervous, we could help you find one that doesn't have that leakage, but you will have to pay more for it.

Hopefully someone with more experience will jump in to help you out! EDIT Lorelei posted while I was composing, she knows her stuff

That shouldn't be an issue with this diamond, it is often seen on IS of superbly cut diamonds and shouldn't be a problem.

Check out the Idealscope of the ACA diamond in this link for comparison.

Hi Peri

 

[Paul-Antwerp]

The pavilion angle of 41.2 is a typo. Or the pavilion depth of 43% is a typo.

 

[coblo]

Paul,

thanks for the sharp eye. There is a difference between the GIA #s which I thought I posted. and the MegaScope #s which I apparently posted. So the Megascope #s are contradictory? Is this kind of discrepancy in the normal range?

Top is megascope #s, bottom is GIA.

thanks again,

coblo

 

[coblo]

from the average of all the megascope angles posted earlier i get 40.9, hmm.

Sorry. I cannot comment.

Given the images and the new numbers on this stone, it looks like a winner to me!!

 

[strmrdr]

the megascope numbers are wonky.
The red scope image and the gia cert numbers agree fairly closely.
The megascope is the worst of the scanners but even by that standards the results are way off reality.
Its a bad scan pure and simple or the calibration of the machine is wonky.

Sorry. I cannot comment.

I smell a rat too.
I have noticed before that the ideal-scope images used by this vendor may not be from the stone they are linked to.

 

[strmrdr]

can you post the link to the stone on their website please?

I think its the megascope thats wonky in this case.
look at the range, there is no way the hearts are going to look like that, and the IS image supports the GIA numbers within the accuracy of the GIA numbers.

There is the stone...
Talk to them about it but im fairly certain the megascope scan is wonky.
Have them re-run it.

Thanks for the advice everyone. Sorry I didnt get the link sooner. I asked the vender about the Megascope and am waiting to hear back.

Paul, do you have a thread(s) to point to in terms of your allegation of IS image switching? Thats a pretty serious allegation.

It seems to me that the prices are unusually low on Exceldiamonds, but there are also a lot of satisfied customers.

Paul said ''no comment''.
I said I have noticed this in the past (2003) - but it does not mean the diamonds are bad - it means the images may be representative (in the companies mind) but not actual images. If you search many of their pages I think you may find your own evidence. I did once or twice before and it was enough to indicate that all was not as it should be. I saved that evidence, and have looked once or twice since then and seen similar examples, so as i say - there is no reason to think it will be different now as the costs of taking photo''s and emplying staff has not got lower.

There was another vendor doing the same thing - I think he has stopped after discussions. Someone recently privately accused WF of doing it to and I checked many stones and found all was OK - remeber it costs time and money to take individual images, crop them etc.

Finally I think it is fair to say i do not believe perfect hearts and arrows patterns etc make more then a ''mind'' difference - so there is no reason that SuperbC diamonds should not be pleasing to the eyes of their customers eyes.

Thanks again for everyone''s help. I''ll volunteer to end the thread.
