I''m going to assume that this is a princess cut diamond. If so, AWESOME choice. I''m sure that will be a beauty. Good luck....

This is a princess cut diamond...sorry I didnt mention that above. What other info would be needed to get a better grasp as to the quality of diamond I am looking at and whether the light output will be awesome or not? Any other comments?

Thanks again

Ben

The problem with posting the same question twice, is that you get reactions on two levels. Let me just copy my reaction to your question on the other thread.

First of all, kudos to Martin for providing you already with some angles on pavilion and crown. Unfortunately, both Sarin and OGI still do not give all the necessary angles to start a preliminary assessment of the cut of a princess-shape.

For that, one needs 2 pavilion angles (P1 and P2) and 2 crown angles (C1 and C2). I have tried to deduct the missing information from what you provide.

Considering that the indicated pavilion angle is P1, and knowing the pavilion depth, one can deduct P2, which should be around 39°.

If the indicated crown angle is C1, then one needs a very flat C2-angle to arrive at this table size with this crown height. I have calculated a C2 of 30°.

If I then check the ''cutting guidelines'' of the upcoming AGS-system, this combination is not on their charts. The closest combination on the charts is at the borderline of the future AGS-2 and AGS-3.

Now, it is very important that this does not scare you. There are a lot of things that I like about this particular diamond. To start, it is very square, which should add to the optical symmetry. Knowing this, the pavilion is not as deep as most princess-cuts, which are cut for weight. This is a very important factor, since the pavilion is the basis of the light performance of a diamond, and I especially like that in this diamond.

As for the crown- and table-area, because of the undeep pavilion, the cutter had to gain some weight there, and chose for a weird combo of C1 and C2.

All in all, based only on the numbers, I would say that this diamond has the potential of being one of the better performers on the current princess-market.

I hope that this helped,

I just purchased a ring from Martin at USA cert and was very very pleased with my purchase. The service was great, I was able to view the diamond before paying for it, and I DEFINITELY got the best price. I checked with dozens of online sites as well as different stores directly at the diamond district. Go for it!
