I have seen the Sarin-update, and I think it is very dangerous.Date: 1/4/2006 9:03:56 AM

Anyone have the GIA Sarin updates for the cut grades?

Garry, this is OT but Paul''s comments made me think of this. Here''s a clip from an AGS ''ideal'' with the new performance-based report. Without evidence, I expect that you guys wouldn''t have believed that a 35.1 / 41.0 stone would have made the grade like this.
What do you think? It is that much different than what Paul is predicting will result from the new GIA ranges?

Nice example of a borderline AGS-0. Definitely not my favourite combo, but with the correct length of lower girdle-facets, this can definitely still get the AGS-0-grade.
Now increase that pavilion angle to 41.6, and you will still get GIA-Excellent, even with a crown-angle of 35.5°. In AGS, such a combo would be an AGS-4, according to the AGS cutting-charts.
And the Sarin-software constantly suggests such combos, when running it on a rough stone with sufficient depth. Imagine the flow of these goods coming on the market.

...Did you leave milk & cookies (and a loupe) next to the hearth the night before the release? THAT would be in true cut nut fashion.Date: 1/4/2006 2:12:57 AM

Hey Garry,
If you want nice ice, you know where to find me.
No need for milk and cookies even.
Live long, mate,
I''ve seen pavilion angles heading down to 41.2 and still getting ideal rating. It was a 34.5/41.2 combo but was still a little suprised to see it get the full out ideal rating, HOWEVER the stone did happen to be a really nice looking stone (HCA of over 3 too if memory serves me right).Date: 1/4/2006 10:53:14 AM

Ah, I see. Thanks Paul. I can only hope that the Sarin sofware supports an ''AGS mode'' in addition to the GIA suggestions.

maybe this has been answered some place else, if so, sorry. but,
with the new GIA ''facetware'' program, it calls for some measurements that I am unfamiliar with. Star % and lower half %. I *think i know what they are in general referring to, but just to be sure, can somebody explain it? Also, is there any way to obtain this information at all? probably not without having it measured eh?
also, how on an old GIA report would one obtain the girdle %, If it just says ''medium'' or ''medium to sl. thick''
man, that is a lot of rounding...

Thanks!
A word of caution to others who may be ''googling'' if you type in ''Martin Haske SAS and girdle thickness'' without any quotes, you will obtain numerous results you probably won''t want to click on, especially if you are at work! probably a better idea to type in
''Martin Haske'' ''girdle thickness'' it gives better results!
