Rookie here. Would this be considered a 1A cut or 1B? Most of the parameters are within 1A but the Crown angle I think is 1B. Where would this land on the rap report? Any input would be great. 1.29c AGS Ideal 0 G VS1 Table: 55% Depth: 61.9% Crown A: 34.9 Pav A: 40.9 Crown H: 15.7% Pav D: 43.1% Polish: Ideal Symmetry: Ideal Proportions: Ideal Culet: Pointed Girdle: Faceted (1% to 2%) Flourescence Inert

Not an expert, but have been researching a lot. I believe that is a 1A.

Can you tell it's hearts and arrows by dimensions alone? I don't think so? Need a firescope I think? -M

The easiest way to know is to fill in the stats on the AGA site and see what score pops up  Why is that important though? AGS has already given it's seal of approval on the overall parameters. What's left to decide here is brilliance - and that the AGS claims to represent, while AGA does not. Some different insight would allow to add information on light return to the AGS grade, not the AGA score... if this is what you are after, of course.

You're right the hearts and arrows is a name they gave to the look under the scope. You stone is a great cut I'm sure it sparkles more than most. Personally I wouldn't worry about the HnA designation. You girlfriend (and her friends) are never going to look at the diamond with anything other than their eyes. To this effect, my opinion is that you shouldn't pay more to have someone tell you it looks like "hearts and arrows" under a scope, when all you really care about is how it looks to your girlfriends eye. This cut reads beatiful. Take a look at it and if it sparkles enough for you, buy it.

You can go to www.gemappraisers.com and use their DIY Cut Grading System. Just input all the data requested, and the DIY will give you the overall cut grade. I would have done it already, but you didn't post the diameter and depth measurements.

Here are the measurements: 6.98 -7.03 x 4.34 Does it matter that the larger diameter is listed 2nd, according to the things I've read, the larger diameter on a round is supposed to be expressed first. Is that correct. Let me know. -M

It's not uncommon for the diameter to be listed in reverse order. When you use the DIY system, tho, you need to enter the larger number first. Since the girdle was listed in %, I referenced the AGS standards to translate 1%-2% into a wording grade. The girdle is thin to slightly thick. Here's the results I got: Cut: Round Weight: 1.29 carats Table % 55 Grade: 1A Crown Angle 34.9 Grade: 1B Crown Height % 15.7 Grade: 1A Pavilion Depth % 43.1 Grade: 1A Girdle Thickness Thin to Slightly thick Grade: 1B Total Depth % 62 Grade: 1A Polish / Symmetry Excellent Grade: 1A * Not a primary determining factor. Final Grade: 1B A comparable diamond is currently available for about $8800-$8850, depending on the Vendor offering the diamond.

Valeria: "Why is that important though? AGS has already given it's seal of approval on the overall parameters. What's left to decide here is brilliance - and that the AGS claims to represent, while AGA does not" This is not at all the case. AGS does not make any claim that all AGS 0 diamonds are the finest brilliancy. In fact, the AGS system is loose enough that a lot of AGS 0 diamonds do not perform very well for brilliancy because they are too deep. Cutters are very smart, and try to save weight while getting an AGS 0. This depends on the public either not being aware, or falling for the hype that every AGS 0 is the same as every other one. It just isn't the case. If you find an AGA 1A stone it will be in the very sweet spot of AGS 0 grading and will, under any circumstance, be a fine example of brilliancy. Even AGA 1B diamonds are slightly stricter in cut detail than the loosest AGS 0 diamond cut ranges. Nearly all AGA 1B diamo0nds will be very good to fine light performers when it comes to round diamonds. In fancy shapes, one must look for great craftmanship and then depend on either the eyes or light measurment tools to know when a diamond is a super, top quality stone for light behavior. Diamonds with 1A to 2A cut standards are well crafted. When combined with data that measures light return of the best levels, you then have a super quality fancy shaped diamond. Hopefully, this clears the air a little. Misinformation is not benefical although we know it was being given in good faith in order to assist others. The future AGS cut grading system will not only look at parameters, but at actual light performance. When these two elements combine at their top quality, one has a fine diamond. David S. Atlas |
