IGI Certification? Which diamond do you like?

[h_dog2]

Hello to all,
I am currently overseas and am speaking to a jeweler regarding a diamond ring.

The rings they have quoted me are all IGI certified. Just curious if that is a recognized certification?

I am trying to decide on a few diamonds right now.

VVS1, F, 1.75ct, $20,500
VVS2, E, 1.75ct, $21,000
VVS2, F, 1.75ct, $19,200
VS1, E, 1.75ct, $16,500
VS1, F, 1.75ct, $15,900

Supposedly, these are all "very good cut"

The prices are very good overseas, just curious on everyone''s thoughts. Wondering if the certification is not as recognized?

Please advise! Thanks in advance.

This thread should help you for opinions on lab grading reports. http://diamonds.pricescope.com/grading.asp

As to your selections, we really need the proportions of each diamond to be able to help you. If you could post the;

depth
table
crown angle
pavillion angle
polish
symmetry
girdle thickness

for each diamond, then we could offer some opinions on the cut. Labels such as Very Good cut don't guarantee you a well cut stone. Also you could drop your clarity unless you have a strong preference for VVS, as VS or even some SI clarities can be eyeclean. Colour, again unless you prefer colourless, you could still shoot for a G or H if you wanted, and still have a very white diamond, I just wanted to mention that in case it might be an option for you!

Hello!

It''s really impossible for me to tell you which diamond I like best without information on the angles and dimensions of each stone - which would allow an assessment of the cut qualifty of each diamond.

Most Pricescope members will advise you that cut is all important in determining the beauty of a diamond, as it is the cut that affects the light return, fire, and scintillation of that stone.

I would suspect that the stones you are looking at there are perhaps not as well cut as they could be.

This means that although you are looking at stones of very high clarity and colour grades, the diamonds may not be as beautiful as you might like.

To give you an idea, here''s an Ideal-cut diamond of similar size:

If you are set on a diamond of that size, you might like to consider if you are happy to perhaps drop down to G, or even H in colour, and perhaps to VS2 or maybe even an eyeclean SI1 or SI2... this might allow you to get a far better cut stone of this size, within your budget.

Of course, I may be completely wrong and these might be very well cut stones.. but the price does suggest otherwise.

If you can post the stats on each we will be delighted to compare them for you.

You are welcome! We really can''t give any meaningful input without that info, so if you could get it, then we can go from there. Have you seen any of these diamonds in person?

If you want to narrow down your selection, you might find the Holloway Cut Advisor a useful tool - it''s great for weedng out the not-so-great diamonds and leaving you just the better ones to focus on!

Ideally, you really want your diamonds to have an HCA score of around 2 or under, with Ex/Ex/Ex scores for Light Return, Fire & Scintialation.

Request Sarin reports on the diamonds. Run them on the HCA if they are rounds or on the gemappraisers.com Cut Class grading tool if they are fancy shaped just to get a perspective on potential cut quality.
