Sarin WebViewer discrepancies...

[perry]

I'm evaluating 2 matched diamonds and have downloaded and installed the Sarin WebViewer software. However, I am mistified by the difference in the results for the same diamond; which affects the HCA scores.

Perhaps someone can explain what I am seeing.

When you first open the file you get the "3D"view. You can also change to a "AGS" Report, "AGL" report, and many other reports.

The relevent numbers are different for each of these reports that you would enter into the HCA:

Here is the actual numbers reported by the various reports (in %):

3D AGL AGS
Depth: 62.1 61.7 61.8

Table: 56.2 56.0 55.9

Crown: 35.1 35.0 35.1

Pavilian: 40.8 40.8 40.8

Culet: 0.7 0.8 0.7

How come the different report features within the Sarin Webviewer report different values for the same diamond?

A related question is in regards to the Girdle Measurments:

The Manufactur Report Identifes the the Girdle Bezels AVERAGES 3.3%; and that the Girdle Halves AVERAGES 3.6%, and that the Girdle Minimun AVERAGES 1.9% (all of those values have a min/max reported and 8 values listed down the table).

I suspect this also explains the wide variation in reported Girdles's in the reports listed above.

My real question.... Which "report" should be entered into the HCA as the most representative of the diamond? (I know that the above info gives 1.5 to 1.8 - assuming a "medium" girdle (the AGL/AGS reports list the Girdle as Medium to Slightly Thick).


Also, can anyone tell me how to get the reports to print. Everytime I try I get an error message about checking my printer settings. My printer settings are just fine and I can print everything except the Sarin reports.

See if your printer is set to landscape when printing .

Different labs have different standards, as does the HCA which favors shallow stones.

I think the best for you to consider is AGS system as it is in the Sarin.

Hope this helps

I tried setting the printer to "landscape" and it did not help.

The error message is "Could not print, please check printer definitions"

What do you mean by the comment that the lab has different standards.

Are you saying there are differnt ways to measure Depth, Table, etc...

Yes... there are different standards that each lab uses.

Since Sarin owns the proprietary measurement patents, people who own different machines have to use different methods.

Depending on what machine is used by the lab may affect their gradings. For instance Sarin uses one method for measuring pavilion main lengths and OGI uses a completely different method, which results in more variance in the reports than I like.

Don''t know why you have this prioblem with the printer.... email Sarin and ask. I think their email is on their site.

I have to talk to their tech tomorrow....Which printer do you have? I can ask for you. Don''t know if they have tech support to people that didnt purchase the Dia Vision software.I also don''t know if you can change it with the Sarin Viewer. The Sarin program does have specific settings for their different reports, and as such have three in the software.

I am guessing here, but could be the only settings it may respond to are the person/company''s computer that generating the report.?????

Good luck.

Perry there will be little difference in the outcomes from the data - the Pavilion is the most critical measurement - and the most accurate on Sarin which is why I took the Aussie agency on and endorsed Sarin over Ogi.

As Roc says - different labs have diffeent approaches - notably in where the girdle is measured - the USA valley yeilds -1.7% shallower results and is why Fred C is able to claim competitors diamoonds are often warped.
Why the depths are different???????

Roc, I do not favour shallow stones - I include diamonds that look good from 14-16 inch viewing distances in my better grades. Others in USA have based viewing distances on 8 inches and 10 inches - which I think is a mistake for anyone other than 20 year olds making buying decisions because they can focus at that distance when closely examining various diamonds.
Slightly shallower diamonds also look better when dirty. Try it and see for your self rather than blindly believe opinions based on previous dumb data.
