so far everything looks fine, but we really need crown and pavillion angles to say whether it''s well cut or not. Sorry, I have no idea about ordering from Mexico. There are some people from non-US here, hopefully they will chime in.

I can vouch for Whiteflash personally, but there are also other great vendors on this site as well.

Hi diamondseeker; other info and the angles are as follows:

flouresence: strong blue (is it baaaaad or good??)
Crown angle: 36°
Pavillion Angle: 40°
Medium girdle.

Anyhow, the GIA cert. says: "Profile not to actual proportions" What does it mean???

Flourescence is usually fine. Only in rare cases does it impair performance. It''s more of a preference thing, and I personally like it!

Crown angle is a little high.

"profile not to proportions" means that the drawing of the diamond on the cert isn''t proportioned liked the actual stone. Not really a big deal if you are looking at the numbers.

Pavilion angle is too low to support that crown. There''s probably a good reason why that stone is $4500

What are the desirable parameters for crown and pavillion angles?

I think I like flouresence too! I can´t wait to see this one in nightclub!

Desirable parameters for crown and pavillion vary from person to person. One thing you can do is plug them into the HCA. If all of the specs get under 2, then the crown/pavillion combo should be fine.

Personally, I like parameters from 34-35/40-41 and an HCA under 2.

usually CA between 32-36, PA 40.4-41.4
But more unorthodox angles, around 30 or 37 CA could work with the appropriate combinations.

Generally, I think the shallow end (lower left hand side of the graph,) you want to be to be above the dotted line, which is GIA's target.

and then on the steeper end (going to the right and up) you want to be below the solid line.

And on the left end (BIC) and right end (FIC) within GIA's box and AGS's box, respectively.

Most people would probably use only the AGS box, or where the two coincide.

And then from there you can start getting pictures.

you don't need it if you're using angles. culets large enough to make a difference are somewhat rare, anyway.

Holloway Cut Adviser
Selected: 61.1% depth, 57% table, 36° crown angle, 40° pavilion angle
The result is for a symmetrical diamond with a medium girdle and very good polish
HCA scores were adjusted Dec. 15, 2001 and Feb. 6, 2003.


Factor Grade
Light Return Excellent
Fire Excellent
Scintillation Excellent
Spread
or diameter for weight Very Good

what do you think julien? It didnt match your parameters. Actually the cross was out of both, doted and solid lines.... I should wait with this one right?
