@purpledaisies:  I BELIEVE EGL just has much looser standards.  Therefor something could be graded the same but the EGL one will not be as high quality.  I think anyways.  Good luck on your diamond search!

From what I understand, GIA grades with a lot stricter standards than EGL. So what EGL grades as a D VS1, GIA might grade as an F SI1. This is just an illustrative example I pulled out of my bum, though.

EGL will grade stones much much much more loosely than GIA.  A stone graded SI1 F color with EGL could very well be an I2 j color on the GIA scale.  You can find a lot of ring sites that debate them.

@purpledaisies:  It is my understanding from the research I’ve done that the specs aren’t quite the same. What I mean by that is if you have a 1ct H SI1 EGL graded stone, if that same stone were sent to GIA for grading, it’s likely it would be graded a 1ct J I1 stone. So while it looks like it’s cheaper, you’re still getting what you’re getting, it’s not really a “deal”.

@purpledaisies:  GIA has much higher standards. EGL can be graded the same but the quality could actually be much worse. I have been told not to buy EGL unless you can see it in person!

It really can. EGL grades more generously than GIA. It’s virtually guaranteed to be at least two grades above GIA, but I’ve heard of at least one case where it was 6!

Example of two grades generous:

GIA will say: J color, SI2 clarity, Very good cut.

EGL might say: I color, SI2, Excellent cut

OR, EGL might say: J color, VS2, Very good cut

(and so on. You have no idea where they were generous, it could be anywhere.)

And if it’s SIX grades off (and you have no way of knowing whether it’s 2, 3, 4, 5, or 6 grades off, except by your own eye and knowing well what the color/clarity/cut grade should be), you might get something from EGL (about that same GIA J/SI2/VG):

“G, VS2, Excellent cut”

Now, you might look at the price and think “hey, that’s an awesome deal on a G VS2 Excellent!” and it WOULD be, but that’s not what you’d get… and it won’t be such a great price at all for the J/SI2/VG you ACTUALLY get, with that flattering but entirely inaccurate paperwork.

Also, jewelers can make loose estimates of how their diamond will get graded by GIA. They know that the best way to sell their high quality stones is with the credibility of a GIA cert (or an AGS cert), and they know the best way to sell their lower quality stones is with the flattering extra boost of an EGL “cert,” and they will choose the lab to send it to accordingly. (And their very low quality stones won’t tend to have a cert at all… the jeweler will happily guesstimate it for you though…with a little helping of generosity of course.)

As you can probably guess, my view of EGL is that it’s hardly worth the paper it’s written on! I’m a totally unqualified diamond nut with a good eye and zero credentials, and I’m confident that even I can perform more reliably and fairly than EGL. And you wouldn’t want me doing your grading.

BTW, it is said that EGL-USA is the better of the EGLs, but, for such an expensive purchase as a diamond, the “better” EGL is still too generous, still in an unpredictable way and amount, and basically, still not worth your time, IMO!

@purpledaisies:  If you see the stone in person and are in love with it, I personally wouldn’t worry which certification it has. If you are ordering online, however, I might. As long as it looks good to you and matches the setting/wedding band, no one is going to ask for your paperwork! 🙂 ALso, great choice with the oval shape – I love it!
