Diamond Certificates

Many customers asked me what is the deferent between GIA, EGL, AGI, IGI or any other certificate?

Well, I feel the confusion of you the customer when you want to buy a diamond online or at your local store, when you want to buy let say a diamond 2 carat with H color and SI-1 clarity and you notice deferent prices for deferent certificates….. You start to be confused and instate of a simple decision it become a hard to understand decision….why is it so confusing?

First you have to understand the mechanism of how diamonds are grated, The company that invented the grading system that we are using today was GIA and the majority of the other companies that are grading diamonds (like EGL that is the biggest certificate issuer) are using the same system, the question remaining is for example: Why diamonds graded by GIA are more expensive than diamonds graded by anyone else?

First we have to agree that any diamond came out from a diamond mine did not come out with any certificate…..When the diamond came out as a rough the diamond was send to a manufacturing for cutting and polishing, when this process was done the diamond was sold to a diamond dealer, this diamond dealer is the one that decide to send the diamond for certification (some decide to sell the diamond as it is without certificate), now imagine that this diamond is 2.00 carat in weight was send first to GIA for certification and then the same diamond was send to EGL for certification (this happen in reality as well).

When the diamond came back from GIA the color grading was H color and SI-1 in clarity.

The same diamond was send to EGL and the diamond came back with a grading of G in color and VS-2 in clarity…. (EGL will grade diamonds 1-2 grade higher than GIA).

When you the customer look on the grading it look like the G color and VS-2 clarity(EGL) is a better deal (grading) compare to the H in color and SI-1 in clarity(GIA)…..The facts are that it is the same diamond with deferent grading . This is a summary of the grading by deferent companies that can explain why H color GIA is the same as G color VS-2 EGL…..
