Obtaining an AGS or GIA appraisal
Posted 31 August 2000 - 10:10 AM
I was wondering how one goes about getting an AGS or GIA appraisal on a diamond (that is set in the ring)? Are there local jewelers that are AGS or GIA certified or do I call somewhere (if so, where) and send the ring off to somewhere??

I'm not sure if I understand your question. Are you looking for an appraisal of the estimated value of your diamond or a lab report reflecting the color, clarity, etc. AGS and GIA do not perform appraisals. They only issue lab reports. Both reports contain info on the Color, clarity, measurements and other additional itmes. AGS also includes a cut grade, whereas GIA does not.
If you are looking for a lab report, unfortunately you will have to remove the diamond from the setting. The labs will not grade a diamond that is set. You can't judge the clarity accurately of a set diamond as inclusions can be hidden under prongs, etc. Also, once a diamond is set it is very difficult to determine the actual color. Do a search on the internet and you will find their websites which will give you their locations.
If you are looking for an appraisal, one person I've used and recommend is rockdoc. He frequents many of the diamond forums. See his site at www.diamondclearinghouse.com. His e-mail is email@example.com. Hope that helps.

Thanks for your comments. They certainly help. I am definitely needing an appraisal, and I suppose I am also looking for a lab assessment. My next question is this: Can a gemologist provide an accurate assessment of color, clarity, etc... absent a lab report to assist in their evaluation? I purchased a vintage ring from a traditional brick and mortar jeweler's personal estate collection that he is liquidating. He is providing me with an appraisal for insurance purposes, however, I am wanting an independant assessment/appraisal to verify the quality of the stone. My primary concern is to make sure that I got the good deal that I think I did. If not, I can return the ring for a full refund. I want to find a gemologist that can provide an accurate appraisal/assessment of this type of vintage ring (circa 1920's). Any recommendations or comments would be appreciated.
thanks in advance. I should get the ring in the mail next week.

For those that want to know the truth about diamonds, just ask.

Yes, a gemologist, WITH THE PROPER EQUIPMENT,
can provide an accurate assessment of color, clarity and cut.
I prefer to have a diamond with a reputable lab report and
as an extra measure, have that report checked by an
independent appraiser. Independent appraisers are tough
to find. I agree with Jan that rockdoc is great. He has all
the new equipment (Sarin, firescope, etc.) and he doesn't
sell diamonds himself. I actually used him for my diamond
purchase. You can e-mail him at firstname.lastname@example.org. You
can also check out his website at www.diamondclearinghouse.com.
