Are there anyone who knows of the American Institute of Gemological Research (AIGR) ? I consider buying a Kashmir sapphire from kashmirblue, which have a certificate from this institute, so I would like to know if it is a trustworthy lab?

I personnaly never have used this lab and it is nothing like AGTA , GIA or even AGL that are very reputed labs. (that does not means it's a bad lab, just that, beeing in trade, I almost don't know it... but I'm French).

About the certificates, I don't like at all the "consistent with...".
That's the way you state when the client comes and tells you it is from Kashmir and you have no indication it is NOT from Kashmir.
I mean that there are a lot of ways to say gemmological observations suggest, proove (rare), state with 90% probability, rather than saying that they do not disproove. 

When I personnaly use this "gemmological data are consistent with my belief" it is usually to say that I am personnaly convinced of something, that a lab wouldn't state that on paper but told me it was possible or probable.
Typicaly I regularly sell sapphires from Burma, but for which my usual lab won't give an opinion on origin because there are too few datas, I would state to the client that I believe that origin is Burma, datas are consistent but nothing prooves it.

Hello Faibos,
Please don't hesitate to ask us questions direct.  We are specialist in Kashmir.  My passion is Kashmir.  I buy rough and faceted stones in Kashmir.  I live in Kashmir.  I am in Kashmir now and will be here until the fall.

Let's compare certificates: 
Gubelin (Switzerland)  "Gemological testing revealed characteristics consistent with those sapphires orginating from:    KASHMIR"
GRS (Switzerland)  "Gemological testing revealed characteristics corresponding to those of a natural sapphire from:    KASHMIR
AGL (NY) Based on available gemological information it is the opinion of the Laboratory that the origin of this material would be classified as Kashmir
AGTA (NY)  Origin:  KASHMIR

Determining origin is difficult.  We have cut Kashmir rough and yet after submitting stones to the laboratories the stone may receive a certificate stating another origin. 

My current technique is to give pieces in Kashmir a confidence rating (even rough).  I offer less money or pass on pieces which do not show strong evidence of Kashmir origin.  They may be Kashmir yes, although my confidence scale has been determined by what the laboratories will say.  I've lost tens of thousands learning this subject.  You may see examples on our "Research" section on the website.  I will spend much more time in the future posting research and inclusion photographs on our website.   

The main reason we may use the AIGR lab is the low cost.  I certifiy inexpensive pieces with AIGR because the larger more reputable labs will charge $250 or more for a single cert.  This may be 50% or more the cost of the stone.  This is not cost effecient and only increases the cost to the end consumer.

I hope this helps.  Enjoy the summer,

He he he...funny they should also be on Pricesope. I don't know much about the more unusal certificates either.
Well perhaps the people at Kashmireblue will allow you to have an item your interested in looked at by a third person

Not a problem. 

The reason we cannot certify every piece with well known laboratories is the cost.  The cost of certificates on stones under 1.5ct at AGL is $285, not including packaging handling and insurance.  Many of our stones under 1.5ct are less than $600 which would be 50% of the cost. 

Warm Regards,

I purchased a Kashmir sapphire from "Kashmire Blue" with an AIGR cert. My local appraiser(well respected GIA G.G.) verified the cert. info. I am planning to purchase more from" Kashmir Blue".
