Comparison of IGI and GIA with my future fiancees ring!
Quote this post and reply to it Post#1 @ 12-09-06 , 12:27 AM


I have been lurking around here for the past couple of months, and decided it might be time for me to actually make a post. After 5.5 years of dateing I have finally decided to pop the question. I am a student so I'm not rich but I did manage to save a decent amount of money this summer to put towards a ring. 2 weeks ago I found THE diamond and had a custom setting made. I'm extremely happy with how it turned out!
The main reason for my posting is that I have noticed a lot of people confused about the different diamond grading establishments, and since my diamond came with both IGI and GIA certification, I thought I'd post the differences between them.

Both gradeings were very similar.

My GIA report was...

weight: 0.66 Carat
Polish: Excellent
Symmetry: Excellent
Clarity: VVS2
Colour: H
Measurements : 5.55-5.59 X 3.45 MM

and IGI Hearts and Arrows Diamond Summation

weight: 0.66 Carat
Polish: Excellent
Symmetry: Excellent
Clarity: VVS(2)
Colour: Near Colourless H
Cut Grad: Ideal
Measurements : 5.55-5.62 X 3.48 MM

So the only differences in it were slight variations in measurements, quite close overall! From everything I have seen, IGI seems to be Very similar to GIA when it comes to Round Brilliants. I'd still prefer a GIA, but just a little bit of comforting information for those of you with RB's that are graded by IGI.




p.s. how does everyone take such great pictures of their rings on here? I tried for 20 minutes and these were the best I could come up with! might be time for a new camera!

Interesting to see the different grading for your diamond. I would have thought more of a difference. Congrats on the upcoming proposal!!! Come back with hand shots

If your camera has macro (tulip) gently press that, but not all the way so it can focus, and then try. I have found it easier to take pics w/o a flash and during the day by the window...

Here's another possibility for why they match. IGI appraisals are usually done on finished jewelry. If you happened to have purchased your ring through Costco, they pair the IGI with the GIA grading report to validate the finished ring holds the correct GIA diamond.
In that case the IGI reports are not meant as independant appraisals to compare against the GIA reports, but rather a summation of the components of the ring--diamond + mounting. That's why the IGI report matches everything on the GIA report except accurate measurements--they don't match because it is hard to measure mounted stones.
Pretty ring and congratulations!!

Nope, it wasn't from Costco. I got it from a reputable wholesaler in Canada. Also the diamond was graded and appraised seperate from the ring, which I had custom made. In this article posted by Johnny Boy...

IGI also matches what GIA is claiming, but only on the round brilliant. It's old, but still relevant. Maybe they are doing a fairly accurate job on round brilliants????

Congrats on your ring. As for the photo, you'll need a camera with a good macro lens.

As far as the diamond, I suspect they used the IGI just to add value on top of the GIA report to illustrate the stone is "Ideal Cut" and "Hearts and Arrows" like you mentioned, which is a very smart thing to do for a retailer if you ask me. Contrary to what someone else, said, I would not throw out any report you have regardless of where it came from, that's rediculous. Someone paid money for that report and it does confirm what your other report states, so it does have value. Obviously your insurance company will have to get you a replacement GIA-graded stone if you have a GIA report should the diamond ever become lost/stolen... and this way you can also insist it be H&A Ideal cut since that's what your IGI report states and maybe you'd be lucky enough to get an AGS replacement stone out of it.

Congrats on the proposal. Appreciate your post since there have been several posts about IGI and GIA and your pictures and details help a lot.
Congrats again on your pending nuptials
