Diamond painting? Still a good diamond?

[tulipsrock]

Hi all : )

I''m new here and am hoping to learn what it means to "paint" a diamond.

I''m considering buying a diamond online. The company emailed me this note about it: "This stone in the new scheme of cut grading would make AGS Ideal in light performance. I included the AGS PGS results which I just ran on the diamonds Sarin 3d model for you. This is taken from AGS proprietary “PGS or Light Performance Grading Software” which we have licensed to us. That is however a stone that would not make current GIA Ex standards as it is painted (something that does not take a hit in the AGS system, yet takes a hit in the GIA system)."

I confess that most of what he said above went over my head. He pointed to an article about painting and digging, but I didn''t understand what it literally means to paint a diamond.

Also, here are the specs on the stone...
Let me know if you think it looks good or if I should stay away from it due to the painting.

shape: round
weight: 1.00ct
color: F
clarity: SI1
AGS cut grade: Ideal
est GIA cut grade: Very Good
AGS light perfomance: Ideal
Optical Symmetry: Superior
polish: Ideal
symmetry: Ideal
Fluorescence: None
girdle: 1.46%
culet: None
Lab Report: AGS
Lab report #: 3010808
width: 6.51mm
length: 6.53mm
depth: 3.95mm
table percentage: 55.87%
depth percentage: 60.65%
crown: 34.94
crown depth: 15.40%
pavilion: 40.88
pavilion depth: 43.16
upper girdle: 36.71
lower girdle: 41.95


Thank you so much in advance for any help/comments/opinions you have!

I think that you would have to be an expert trained in spotting this to even notice a dif. Even side by side with one that isn''t slightly painted, I think that you would be hard pressed to see the dif yourself.

If the AGS gave it an ideal for light performance, that''s good enough for me. The hair-splitting between GIA and AGS about this has been done a lot here. It looks like a nice diamond. Don''t worry, enjoy.

Presuming it's crown-only painting - the term just implies brillianteering where the angles of the upper girdle facets were brought somewhat closer to each other than traditional brillianteering.

If the optical symmetry (H&A) of the diamond is good - as it's advertised - and it's not too shallow such crown-only painting can give a diamond a more fluid look to scintillation that some people actually prefer. The Eightstar brand (the first 'superideal' diamond) was the first to use this method to create what some call a broadflash effect by using painting. The word "painting" got an undeserved bad rap when GIA released their cut grade in 2006 - it penalizes any diamond for around 4+ degrees of painting, regardless of configuration. The AGS evaluates each diamond on its own merits - steep diamonds are actually helped by painting but it's the kiss of death for shallow - and this diamond, in their metric, earned the top grade.

According to what the company told you (assuming crown-only painting) and with those proportions I'd expect that this diamond has between 4.X and 6.X degrees of painting, as per the chart below. If this is the case and the diamond has great optical symmetry I second Shay's prediction above.

If you like putting bamboo shoots under your fingernails on a Friday evening you could search "painting" on this forum. You'll find people on both sides of the issue... We've got it surrounded. Only slightly less painful would be a complete read of this very technical brillianteering article in the PS journal. You can read the minutia all day and night, but once you see the diamond you might just laugh and wish you had those hours of your life back

Thank you for your replies so far.

With the specs I listed initially, would $5,400 be a fair price?

Does painting have an impact on a diamond''s price?

John, I should have prefaced with this. Thanks for squaring me out. I just was making the assumption that it had to be slight and crown only to get the AGS ideal. My bad. I should be more expansive for the newbies.

I bet the diamond is killer!

I LOVE that the cutter got to the magic 1 carat mark without sacrificing beauty! The numbers speak for themselves.
