I need to find newest AGS charts

[risingsun]

Please help me find the charts for the most current platinum and gold grading reports for the AGS. I would really appreciate it

Hi, Marian,

You know, what I turned up doesn't seem right, really, but it may be, and it's all I readily point to.

In the pinned "helpful threads" thread, you get this thread:

viewtopic.php?t=123202

pointing you to the history of patterns of types of reports. But, the only quick & dirty for what would be Platinum, and this is probably what you want, dates back to 2004, but may be correct, is in FAQs, and is here:

faq1/ags-and-gia-cut-comparison-charts-t41793.html

I wouldn't bet money this is the most current info, but it wouldn't surprise me if it's the only info we published, either.

Best,

There you go. http://agslab.com/trade_research_and_development_cut_grade_documents.php

Stone, do you know, is the deal that, if you make those proportions, you get the grade in gold, but for platinum, they are only guides?

Seems like I'd seen in some older threads there may have been slightly different criteria for the 2 systems.

Guide, should be Pt. I believe Gold has another set of numbers.

Guide, should be Pt. I believe Gold has another set of numbers.

To the best of my understanding the guides represent a theoretical diamond whose exact proportions(perfect symmetry) evaluated by their performance based grading software would obtain those grades for a platinum report.

The guides for cutters:

1) Isn't the same as the gold proportion based gold grading as it doesn't mean a stone with those average proprotions is guaranteed to receive the grade.

2) It only applies to a stone of those exact proportions with every crown and pavillion angle the same. Slight assymetry could lower the grade especially for borderline combinations.

3) The recent platinum grading report is performance based (ray traced data set) and the following makes up the grade:

Final Cut grade = Maximum(Sum(Brightness ,Dispersion ,Contrast ,Leakage ,Weight Ratio, Durability ,Tilt), Girdle, Culet, Symmetry, Polish)

The first 7 are a cumulative deduction.

Hi guys . Thanks for your help. Do you remember that Garry posted cut charts that compared the Platinum DQF charts with the new new gold standard proportion based DQR. He had pages of material, divided, I believe, by table %. That is what I am looking for for. Did he get the charts from Serg? I remember them, but cannot remember the data. Maybe this information will help.

Thank you, Stone!! There is one more chart that I'm looking for. It is the comparison between the AGS Platinum DQD and the new AGA "gold standard" DQR. I know we had it on PS because I spent considerable time comparing the two. I appreciate your help

I meant to say "...the new AGS" gold standard DQR."

 

[stone-cold11]

It is on the same page, that is the AGS Gold, further on the left is the AGS Plat.

On the same chart only the 57 table is there. http://www.octonus.com/oct/mss/ags2008-pgs.phtml

Best,

Thanks for the links, Ira. It wasn't exactly what I was looking for, but it is very good information to have. I need to start keeping a file. You should see the notes all over my desk
