Who prepares ''certificates''?

[denverappraiser]

Good moring diamondphiles,

I have a project. I'm preparing a listing of as many of the labs as possible that issue diamond grading reports. My plan is to prepare an index of the currently available reports and a link to the issuing lab. What I'm looking for is reports on diamonds only (no other stones) and for gemological reports only (not appraisals). Here's the beginning of the list. I know that there are important omissions and probably errors. As this thread progresses, I'll update the list to contain any additions or corrections that people may have and will then prepare a more concise document to post in the journal section. The labs appear in no particular order other than the 'major' labs are listed first. I'm also planning on including a scan of a genuine example of each of the subject reports. If you are with one of the labs, especially one that isn't listed, and you would like to be included, please email me a scan of a sample of one of your reports. If your lab has additional varieties of reports that meet the above description, I'm happy to include a line for each and every type of report you produce.

Special note: Presence on this list does not constitute any kind of endorsement of these companies nor is it in any intended to disparage the firms who are absent. It's merely intended as an listing of companies who issue documents that are either described by the company themselves or the general consuming public as causing the diamond to be 'certified'.

Hopefully this will produce a useful document.

Neil, the SGL Comprehensive Diamond Analysis contains more information than either an AGS or GIA report, but like the GCAL report includes a valuation as well.

I issue CDA's without a value if requested, but often the reason my clients come to me is to gain information which is lacking on the "major" lab reports.

I wish I could sit around all day issuing reports without a value. It would make my life a lot easier.

 

[denverappraiser]

Rich,

I certainly understand. Perhaps I should eliminate that restriction from my list. The reason I put it there was that we get lots of questions here about diamonds being 'certified' by some lab or another and it seemed like it would be helpful to create an index of these various products. If what the poster is really describing is an appraisal, then the list of possible suppliers will be extremely large and consequently not very useful. I certainly didn't what to exclude any that should be included but I don't want to list everyone who calls themselves an appraiser either. Any suggestions?


Storm. Thanks. I'll edit the original list so that it's easier for other people who read it. I forgot all about PGS. Should I include GQI (a previous name for that company)?

If they currently dont use the name I wouldnt include it I think.

 

[denverappraiser]

The reason I considered including them is that I still occasionally see their documents and consequently some people ask about them. The same can be said for the old EGL-LA lab.

Neil

hmmm yea include it then with a note that they are now pgs I guess...

 

[denverappraiser]

Can anyone contribute a scan (front and back) of one of the missing reports?

Neil

 

[PhillipSchmidt]

Neil, if it is of any help.

There are two more in Australia. DCLA is one of them and they are supposed to be good. I don''t know much about the other, but it starts with ''A''

I noticed Anchor cert and they make some pretty strange calls. If you don''t like your cert try again, sort of thing. They are better then that and probably do as much work. The certs have pav/crown angles.

Cheers,

Phillip

 

[denverappraiser]

Phillip,

I''ve added DCLA. I would love it if you send me a scan of the front and back of one of their reports as a sample. I''ve never seen a stone or a report from Anchor. It looks from their site like they are a US firm. Are they doing business in Australia?

I may actually need to change my formatting a bit because there are so many names that there are shared acronyms. GGL and NGL have more than one company. Yikes, this is a bigger list than I was expecting. I haven''t even looked to see what is being promoted on ebay and similar venues.

I used Anchor cert when I worked in Birmingham. I am not sure what affiliations they have. They share premesis with the Brum'' assay office.

They are not in Australia.

There are two in Oz but DCLA is all I have used. I expect the other is pretty good too.

I have added a photo of a DCLA cert. Never even looked at the back, sorry. Their web site is good. I expect they will help you by send some more scans.

Hi Neil
You may want to add The South African Jewellery Council Lab. They where established in 1978 and grade to IDC rules ( so do HRD)

[WinkHPD]

I wold definitely NOT put GQI on the list as Tom Tashey is prohibited from using that name as part of his breaking away from EGL. His PGS cert is a very good one with many of us in the trade and while I do not think he could be liable for your use of a name he is prohibited from using I do not think that it will benefit him in any way either.

The Tashey''s are wonderful people who have been a great assett to the gem trade. In my opinion, and in the opinion of many in the trade PGS should be listed above EGL in the issuance of quality reports on diamonds. Many of the stones I carry are PGS papered and those that I have sent in to have graded by AGS have all been within one grade. Most were the same grades, but even between GIA and AGS there is frequently a difference of opinion, as shown in the study done by Leonid and Gary Holloway some months ago.

Those of us who know the reports and who use them regularly are quick to accept one of their PGS reports, unlike those of some of the labs listed above which we automatically assume to be one to two color AND clarity grades off. I just delivered a stone Friday with a brand name report that I bought VERY cheaply and had recerted by GIA. My H-VVS2 became a J-VVS1 when regraded. I agree with the VVS1, but I think the stone closer to a K than a J, and NOWHERE in the neighborhood of an H. Since I paid K pricing on the stone I was happy, but someone who did not know the market and who paid for the H would justifiably be incredibly cranky.

Sorry for rambling on. I am glad someone (thank you storm rider) quickly mentioned their name. I will be interested in seeing your final list.

[denverappraiser]

Johan,
Thanks, I'll add them. Is there a listing of labs that comply with the IDC rules? Do you know who the other Aussie lab is that Phillip discussed?


Phillip,
The reason I asked for the back side is that this is often where the disclaimers and explanations appear. For clients who wish to understand what their report means, this is important information. In the case of the DCLA report, it looks like this appears on the front. This is especially important for the smaller labs or for products where comparatively few people are familar with the details of the report.


Wink,
I certainly don't mean to cause any problems for the Tashey's. I agree that they offer a fine service. This list is not intended as a recommendation of anyone listed and I agree that there are definitely some reports listed that I do not consider to be especially valuable. The idea here is to produce an index that will be useful for consumers who buy a diamond accompanied by one of these documents. My hope is to create a resouce where they can look up the document they have, see a sample of what a 'genuine' version of that particular report looks like and have a link to the site creator where they can get further information if they choose. I've considered suggesting to Leonid a discussion thread for each one of them so that people can comment on the merits of the lab or that particular report. I included GQI because I still periodically see reports with that brand. How about if I just list it as 'no longer in business' and avoid connecting them with the Tasheys?

RE: How about if I list them as no longer in business...


Hmmm. Not sure if that is good or bad. I bet if you called Tom at PGS and asked him he could look at this thread and ask you to do it one way or another. I certainly do not want to say, "Hey, you should ..." when he might prefer it another. Besides, who the heck am I to be telling you you should about anything?

I like your idea about having an additional bit of informatory resource at Pricescope, it is after all, all about information.

Hi Neil,

Thank you for including us.

The DCLA grading report can be veiwed on our website: dcla.com.au under "about us" "Cert Guide".

Here is a list of IDC laboratories from the World Federation of Diamond Bourses.

"The IDC Rules are the diamond grading guidelines devised by the International Diamond Council (IDC), which was set up in 1978 by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA). There are currently five gemological laboratories worldwide that apply the IDC Rule Book. They are
1. The Certificates Department of the Antwerp Diamond High Council (HRD), Belgium;
2. The Swedish Testing Institute, Stockholm, Sweden;
3. The Jewellery Council of South Africa Laboratory, Johannesburg, South Africa;
4. The Diamant Prueflabor, Idar Oberstein, Germany.
5. The Diamond Certification Laboratory of Australia, Sydney, Australia; " -- WFDB Newsletter No 6

Best regards

Roy Cohen

Hi Neil
I see Roy Cohen of DCLA has answered your one question,
I doubt you will be able to download an image of their cert as I think they have a flash site. If you need a good image we have plenty of their certs and would be happy to scan one for you, just let us know

The other Lab in Australia would be Gem Studies Laboratory of Sydney, I don’t think they have a website but they have been around for a while. E-mail is [email protected]

Regards,

Johan

 

[denverappraiser]

Roy and Johan,

Thanks for the information. I''ve added them to the list

There are (or at least were) several labs in Japan. Is there anyone here with information on any of them?

Neil

 

[PhillipSchmidt]

AUSCERT

http://www.auscertdiamonds.com.au/index.shtml
This is the one I was thinking of. Three in Australia and counting...

From the Home page:

"In 1980 we established an independent organisation in Australia called Scientific Gem Testing Laboratories (SGTL for short), where you can obtain an AUSCERT Diamond Certificate. This Diamond Certificate will give you the information you need to reassure you that you''re making the perfect diamond purchase".

They are a hard one to guage from their web site. Seem more like an apraiser, but it looks like they are stocked by a few on-line stores. Don''t know what to make of them.

Phillip

Johan,

eeek

I''m going to need to put some thought into the formatting of this whole thing. We have quite a few with a contact address and no website and quite a few with multiple different labs where the reports can be considerably different depending on which lab issued it(iEGL in particular). I''m thinking a database style format with the following fields.

Lab Name
Lab Address(s)
Acronym
Product Name
Photo front
Photo back
Link to the company
Link to discussion

Anything else that should be included?

If you really want to go nuts contact each and get a marketing speak blurb from each about the services they offer and add it in.

I have seen in one local shop rings zip tied to a BGS report.(about a business sized card that was laminated with holes to zip tie the ring to it.
BGS - British Gemological Society

will have to google to find out more

They can post their marketing on their own site where they have free access to update it as they see fit. I''m thinking a thumbnail of each flavor of report would be helpful for the benefit of people who buy a stone and want to do some research into the attached documents. It looks like we have about 60 reports so far from about 40 different labs. There are a couple, like GCAL, that do private label reports where someone elses name appears in the masthead and the GCAL name is in the fine print. A flash tour like the DCLA guys have done would be lovely but I don''t want to work anything like that hard.

Thanks Summerisle, I''ll see what I can find out about them.

I may have created a Frankenstein.

the only one i found was the British Gemological Association... or Gem-A - at http://www.gagtl.ac.uk/

But the sample report and the logo does not look the same as the one i have seen on one shop... so next time im near. will have another look in the window to find out. (tho it seems there is a BGA - part of IGI)

 

[Lord Summerisle]

Well i think one mystery has been solved... having looked at thw BGI site.. thats who the certs where from in the Shop i visited.

OK gurus, How do I sort this out?

It looks like two different labs with identical names. Jeez, this is getting complicated.
