EGL Foreign vs. GIA

[Brian Knox]

There are always posters asking about EGL foreign labs and how the grades compare against GIA graded diamonds.

Here is an actual example of a diamond that had been submitted to both labs ( GIA and EGL Israel (I think)

I offer this with no malice, but simply as an educational post for the benefit of PS readers.

LAB COLOR CLARITY CURRENT RAP PRICE PER CARAT

GIA G I-1 $4200
EGL FOREIGN F SI-2 $6900

Heres the EGL...

This stone is another example Brian - we keep one of these in each of my 2 stores as a little "buyer beware" lesson. I paid 1/2 half as much for the EGL stone as the one on the left - the dealer market is not silly, but consumers can be

A sample size of one is dangerously small!

It is 3 so far RA.
I also submitted a stone when I was in Israel to EGL some years ago and got a silly grade.
Local folklaw suggests you can send the stone in a rivka and they will grade it at what is written on the paper flap. I do not think that would be true as they should be running a blind book in facility.

But what is really scary is that EGL have the SI3 grade and that is supposed to mean that they can run a tighter SI2 because the border line stones are called SI3.

EGL-USA gets a bad rap from many here. I''d love to see the same stone again submitted to EGL-USA to see where it comes out.

Brian,

I notice that, in addition to the clarity and color, the two reports also differ on Width, Depth, Girdle, Polish, and Symmetry.

Thanks to all. Proceeding with extreme caution.

Hi Neil,

You know what the say about reports.

There are a few facts, everything else is an opinion.

The date is a fact, one hopes that the weight is a fact, past that , there are only approximations and opinions.



It does bother me that we can send a man to the moon but cannot get the labs to agree on measurements.

Although, I don''t lose as much sleep over it as I used to.
