The Precious Stone Lab London Diamond Certificate

[simon123]

Hi Everyone,

I bought my wife's engagement ring about 13 years ago and it was certified by the The Precious Stone Lab of London. I would like to get it recertified by GIA, do I just take the ring to my local Jewellers. Will the diamonds need to be removed also? How credible is the current certificate? Thanks for your help.

you don't have to take it to jeweler except to have the stone removed. Yes they only take lose stones. Simply go to the GIA web site and it will walk you through how to submit the stone by mail. I am assuming your in england. The turn around time is long right now. It will also give you a better idea on the web site the fee and the waiting time.

i have never heard of the prescious stone lab so i'd take that certification with a grain of salt. How large a stone are you talking about. its worth it just to have it indepantely appraised instead of certified. Personal choice...

The Birmingham Assay Office acquired the Precious Stone Laboratory about 10 years ago & hired Eric Emms, the Precious Stone Lab's founder to oversee the launch of the Assay Office's AnchorCert Gemological Service ; see this 2004 press release:

Mr. Emms, who left the Assay Office about 6 years ago to offer gemological classes-coursework, didn't come out of nowhere

so the fact that I, living in the States, hadn't previously heard of the Precious Stone Laboratory isn't enough, in and of itself, to make me doubt the validity of the the report you received.

A new GIA report, however, would make the stone more marketable, if you are thinking of selling it. But if you want a 2015 report for insurance purposes, I'm thinking that Safeguard, the appraisal division of the Birmingham Assay Office, would be a better choice:

P.S. If you are keenly interested in receiving a GIA report, it may be worth your while, both logistically and cost-wise, to have your local jeweler handle that through the Gemological Association of Great Britain's GIA service rather than doing it yourself:

Hi, thanks for our reply. The stone is 2.08 on a H.

Excellent idea - I will go ahead and do this. Thanks again for coming back to me.
