Umm...re point #2, I wasn't making a defamatory comment on NAGL. I am merely repeating what I have heard for years now, GIA and AGS are the only labs that grade properly, everyone else you can expect a grade or two difference in color and clarity.
I'm not making this up, sorry if it upsets. Glad to hear there are GIA graders at NAGL though.
I understand what you are saying in general, as we have been burned by buying an EGL Europe F diamond, recutting it to H&A proportions, and then sending it to EGL US where they promptly graded it H color....apparently EGL Europe is notorious for lax standards but we didn't know that years ago.
However....while that may be true in some cases, making a blanket statement is not the right thing to do.
And, posting false information with the claim that you are 'merely repeating what you heard' is still posting defamatory comments.
And in this case it would be 'libel per se' b/c it impunes someones ability in their profession, meaning an easier case with more damages.
The US (and likely UK) legal system doesn't care if you are 'repeating what you heard', false statements that you publish are your responsibility.
Would it not be more productive to leave out the defensiveness and sarcasm in favor of facts. Fact is the lab has GIA gemologists and therefore would grade similar to GIA.
Specifically for NAGL - if NAGL has 2 former GIA graders as their only graders, meaning the same graders you would get if you sent it to the GIA just a couple years ago, how could there be a difference between GIA and NAGL?
The graders lost their ability to grade once they left GIA? The logic isn't there.
