AIG labs trustworty? anyone has experience?

Recommended Posts

Dear people of diamond review,

Does anyone have experience with AIG labs? This is a link to their website:
https://www.aiglaboratories.com

A lot of jewelry sold on catawiki has AIG certifications.

I couldn't find anything about them on google except from this forum post from 2005:

Greetings,

Olivier

Hi Olivier, welcome to Diamond Review!

A couple of old threads mentioning AIG...

https://www.diamondreview.com/forum/topic/4577-first-time-robbins-bros-aig-cert-scary/?tab=comments#comment-18786

https://www.diamondreview.com/forum/topic/11287-some-diamonds-expert-please-help-me-thank-you/?tab=comments#comment-60473

where you will see that the opinion is basically as follows (and I hope that Neil @denverappraiser will forgive me if I borrow from him):

1. Anyone can set up a gem lab. No qualifications or expertise are required.
2. This means that the default answer to "can I trust this lab?" is no - they need to earn your trust either via their reputation or your direct experience with them.
3. AIG is not well known, and I assume you have not dealt with them. Be careful!

Bear in mind that the report that a diamond is marketed with is not a random choice by the seller; it is a very definite marketing tactic.

Thank you!

The fact that I see tens of rings being sold right now with AIG certfification, would lead me to assume there must be people who've had recent experiences with them (either good or bad) and have posted about it, but the fact that I can't find anything about it seems weird.

Many sellers (all Israëli) have a lot of reviews and over 99% satisfaction rating and they use AIG for every piece of jewelry:

I am not trusting them, but I am curious how this works, and it might be interesting information on anyone googling them.

Well...

couple of observations:

1. The vast majority of diamonds are sold with no lab report at all. At best a description from the seller which may or may not contain any details beyond weight, and if it contains anything else it may or may not be accurate.

2. The three vendors you have linked have in total ~130 items for sale (some of which are not accompanied by a lab report). But let's assume they all are, and all the reports are AIG. There's another 2,800 auctions for diamond ("diamant") on Catawiki. Let's say that 90% of these are "AIG" - total "AIG stones" advertised: 2,650. The three retailers have a total of 1,150 reviews - or ~10 for each advertised piece. Multiply that total by 10, and we arrive at 26,500 "AIG" stones ever marketed via Catawiki.

Here is the link to the round diamonds advertised by half a dozen diamond retailers on this website:

https://www.diamondreview.com/diamonds?sortOrder=price&sortDesc=1&fShape=Rnd&fCaratLo=0.01&fCaratHi=200.00&fColorLo=D&fColorHi=Z&fClarityLo=FL&fClarityHi=I3&fCutLo=&fCutHi=poor&fDepthLo=0.0&fDepthHi=100.0&fTableLo=0.0&fTableHi=100.0&fSymLo=&fSymHi=poor&fPolLo=&fPolHi=poor&fCulLo=&fCulHi=vlarge&fFlrLo=&fFlrHi=vstrong&fPriceLo=0&fPriceHi=1000000000&adv=1

There's 409,000 round diamonds advertised; plus another ~160,000 in shapes that are not round; I'll use "round only" in the next paragraphs. Some diamonds are advertised by more than one retailer, so let's take away 10% of the count for duplication.  Total "unique" stones advertised: 368,000. Of which 98% have a GIA or AGS report; that's 360,000 stones.

There are more out there... and these are the ones for sale, not the ones sold. Some of the advertisers here, like Blue Nile, have sold literally millions of diamonds over the last 20 years, most of them with a GIA report. Note that the largest lab in terms of volume of reports is probably IGI, and - because of the market that these advertisers cover - IGI stones are a small minority of those advertised here.

Might is not equal to right - the only point I'm trying to make is that your sample is a bit biased and AIG is a relative minnow compared to GIA, IGI and HRD (which are the truly "big guys" in diamond gem labs). For whatever reason, some people on Catawiki sell AIG diamonds; whether that's because the buyers don't know, don't care, or trust the sellers, I have no idea. But given the relative volumes, it's not particularly surprising that there isn't that much feedback on AIG.

All this said, totally agree that the more info there is out there, the better!

There's a large company called "American International Gemologists" that produces sales documents for jewelers, mostly online, with the masthead AIG. They make them by the thousands. Your headline and URL is for "Antwerp International Gemological Laboratories". These are not the same. 

 The heart of your question is simple enough. A seller produces a report from AIG that says something. Should you believe it?

Maybe. Maybe not. The merits, or lack thereof, of AIG is on them, not the seller and not us. The fact that the seller chose them tells you that it's their guys, not yours. The fact that it includes at least some information that you know to be false is a bad sign. The fact that you are having a hard time researching them is a bad sign. 

I took the opportunity to look up a more-or-less random offering on that site.  Like the ones you're looking at, it's being sold by an Israeli dealer. Several things came up in a brief look. They supply a clarity grade of 'transparent' on the ruby. That's not even one of their choices on the clarity scale they include right next to it.  They missed some critical information, notably treatments or lack thereof on the ruby. That's a huge deal in the ruby business and it's the #1 reason people would want to see a lab inspection report. They don't even say if it's natural or synthetic. They give it a cut grade, which has no scale at all. The jewelry has an 'excellent ideal finish'. I can't even take a guess what that means and, again, no scale or context is given.  Does that make them wrong or unreliable? Absolutely not, but I'm not sure what you would rely on them for. 

Then there are those reviews.  138 of them. I didn't read them all but it seems to be full of comments on how happy people are with the shipping speed. That's a fine thing, but it has nothing to do with the reliability of the paperwork provided. I didn't spot a single one that talks about the subject at hand here.  Maybe I just missed it.
