I would be extremely wary of an IGI graded stone--can you have it sent to an independent appraiser before purchasing or is there a guarantee so you can return the stone if it isn't what it says? I would just hate for you to pay for a "D" and find out it's not. Also, the fact that it's eye clean means different things to different people (it's considered by most to be eye clean if you can't see the inclusions from like a foot away and looking just through the table). To me, eye clean means a stone that doesn't have any visible inclusions no matter how close to your face you hold it and what angle you hold it at. So, make sure your definition of eye clean matches theirs!

It's a touch on the deep side. 5.81/9.33 (avg diameter) = 62.4%

Using the HCA with %'s is not as accurate as it would be if you had angles. Based on the specs you provided I got a score of 2.1, Ex/Vg/Vg/Vg, with the comment of "Worth buying if the price is right".

The asking price could be fair. Depends on the Cut Class. I would suggest you ask the Vendor for a Sarin Report, then crunch the HCA again, and use the DIY Grading System at www.gemappraisers.com. Verify the quality of the make and check Price Stats, link at the top of the page, to see if the asking price is indeed fair.

You also need to make sure what "eye clean" means to the Vendor and how that description fits with your own personal expectations. Larger carat weight SI1 diamonds are much more likely to show inclusions thru the side. Especially larger carat weight D color diamonds. It will really depend on the size, type, color, and location of the inclusions. You might ask the Vendor for pics of the diamond and magnified pics of the inclusions to help you decide.

It looks like this diamond is worth investigating further. Get some more detailed info, though, so you can make an informed buying decision.

Thanks guys for your soooh prompt replies.
The situation is that I live in New Zealand and our
local gemologist is at a Diamond fair in Hong Kong looking
for a diamond for me. She said the stone is "eye clean"
and is fabulous and a real sparkler. I was a bit iffy
about the IGI Cert but the gemologist's assistant here
in NZ said there is an interrnational standard of
diamonds used for all colours. Apparently there is 1
inclusion on the side but it reflects so looks like 2?
The gemologist doesn't have to buy the stone - it is from
the cutter but her advise is that its good. I've asked
for depth so I can put on Holloway Advisor and she is
going to try and get Sarin report. All feedback is most
welcome. Thank you.

There is an international standard, but some grading organizations are more lenient than others. I'm not saying you should stay away, but that you should really make sure you're getting what you pay for (although not desired, it is acceptable for graders to be off in color and clarity by 1 grade).

Have you used the "price stats" link here on PS to see what similar stones in the 1A cut range are going for? I did a quick search and discovered that, while you're in the right range, this stone is priced a couple thousand dollars more than similar stones. It might just mean this is a better stone, but I'd make sure before you buy it!

Good luck and I'll keep my fingers crossed for you!!!

Could some offshore merchandise prove tempting ?

Such as this GIA pieces (LINK) or THIS

The H&A collection at Mondera, Icestore, and some further inquiry among sellers could produce options too, if you choose to look for some.

It seems that IGI's word comes at a discount around here and not so at your provider. Otherwise, enither you not I have seen the piece to jusdge the accuracy of those grades and the H&A claim.

Just input your proportions to DiamCalc.

Your percentages provided suggest a 41 degree pavilion angle and a 34.3 crown angle. The 41 degree pavilion angle is a transitional angle which means the diamond may be a leaker or there may be no problem at all. Only real way to tell is with a physical analysis of the diamond with optical exam. However the 34.3 crown angle suggests positive things and there may be no prob at all.

Here's the stats of your stone as entered the the angles it is suggesting. The slight dip over 41 is what's causing the HCA score of over a 2, which may in fact be a little misleading in this case.

This isn't the end of the story though as the percentages/angles of the minor facets (40 facets total out of the 57) can impact it's optics one way or another. Below are 3 examples (out of hundreds of possibilities) where your stone may fall and what optical aspects are emphasized.

Hi Rhino,
Thanks for doing the analysis for me. After 5 months
reading this forum I still wouldn't have a clue how
to get the results you just did. To me the stone looks
stunning. I have asked again for more details of the stone
but as mentioned above unfortunately they are at a fair
in HOng Kong and the IGI Certificate is dated 17 June
2004. The cutter usually gets an HRD cert as well but
because they were in a hurry to take the stone with them
there was not time. As said above the jeweller who has
checked the stone said it is stunning. She has checked
the hearts and arrows and said they are perfect. The
imperfection can't be seen with the naked eye and she said
she had trouble finding it with the 10mm loop.
Valeria - I would love to buy from USA the problem is I
would have to pay an additional 12 1/2percent tax to have
the stone landed in New Zealand or else fly to Hawaii or
Los Angeles to pick the stone up and then wear it back in
to NZ as personal effects. Then I have cost of flight!!
This does limit me. I have been drooling over Good Old Gold
diamonds for months and love all the detail given - which
gives you much needed confidence when shopping over the net.
My first purchase was a 2.06ct I SI1 good cut round brilliant which I have been disappointed with (surprise) so
this diamond is my upgrade. I will then purchase another
2.06ct I SI1 and make a pair of earings. 4cts. of bling
- that should do it!!
The gemologist has also said she will get two independent
appraisals when she gets back home and then we will get
all the figures.
My nails are now bitten to the quick.
Thanks so much for taking the time to clarify things for
me
