We didn't see your other post, so we don't know exactly what you were asking, but it sounds as if you are probably trying to verify the details of an EGL issued lab report? This can be a bit of a challenge because the EGL laboratories are franchises, thus they don't share a common database and each laboratory is operated individually... So you need to determine which laboratory issued the report, the easiest way to do this is to contact one of the laboratories and ask them to help you make this determination. You can begin your quest here

We've never head of the web site you referenced, but it may be a doorway to one of the more popular sites... Regardless of who they are, we recommend contacting the Jewelers Vigilance Committee
http://www.jvclegal.com or is it .org? to ensure that the company does not have any unresolved complaints filed against them before sending them your hard earned money.
