what do you think of this ASET pic?

[Maxine]

This is an ASET pic of a diamond I''ve been looking at......what do you think???

 

[Kaleigh]

Maxine,
Looks great to me!! What are the specs???

 

[belle]

the symmetry looks great!
i like good symmetry

 

[Garry H (Cut Nut)]

great stone
great photo - was it taken on thedesk top or with a hand held?

 

[Maxine]

Hand held.......is there anything else out there at this point????

Is the inside circle the "right" color??

 

[Garry H (Cut Nut)]

The color of the inside can be red or green.

IT IS NOT AN ISSUE with AGS grading (no matter what anyone may tell you)

Maxine,

I hadn''t posted them....was wondering if any experts could tell from looking at the pic what the possible specs would be....?

(Just curious as to how much one can tell from these pics.....)

anyone with diamcalc can do it more accurately than Sarin or Ogi scanners


http://www.ideal-scope.com/Using%20DC_files/frame.htm
DiamCalc - Estimating Proportions

•Estimate diamond proportions using Ideal Scope photos of loose or mounted round brilliants
•In about 5 minutes you can fairly accurately estimate proportions without a $5,000 to $20,000 scanner
•Size Ideal-Scope photo to about 400 to 600 pixels
•You can do the same with a visual examination, i.e. without a photo.

This little magic trick works pretty well and it actually easier with ASET photos than with IdealScope photos because the colors make the facet junctions easier to see but I would not go so far as to say that anyone can do better than Sarin. How the photo is taken is important and, assuming that someone else took the picture, it's impossible to tell how it was done.

Not an expert, but I'm game to try completely by eye.

Small table 52-53%

Pavilion a hair deep, 41.2-3 degrees

Crown, becasue I'm saying small table, I'll say crown under 34 degrees

The proportions of the shafts should be telegraphing the LGF%'s, but I can't remember which number goes with those proportions. Maybe close to 80%, but it's really too sensitive so this is a wild guess. There's a post around that would make this easy.

Anyway, is any of this remotely close? (so to speak) If so I will very surprised.

 

[Garry H (Cut Nut)]

Here are the proportions

(Arthur did it - I have not changed anything)
But someone sent me a link to the stone and it is possible for me to see the proportions - I have not yet.

 

[Garry H (Cut Nut)]

The star facets are very long, 64% which is why there is a color difference at the upper girdle junction. But the stone works because it is in the sweet spot.
Lower girdles are estimated at 80.4%

We have no dimensions so can not do girdle thickness.

here is the DiamCalc image from the estimation

 

[Maxine]

That pic was taken by Jonathan at GOG....(in a hurry, also, I think....he did it on his way out the door the other day so that I could see it....)

the specs from his sarin are:

depth 61.2
table 55.7
crown 34.4
pav 40.8
girdle 1.6
culet .03

 

[Maxine]

Edited to:
culet is .3 (sorry)
and diameter is 5.6 (.65ct)

 

[Maxine]

This is Jonathan''s lightscope of the same stone.....

 

[Maxine]

...and measurements............

 

[Garry H (Cut Nut)]

OK, thanks Maxine.
I have played with arthur''s model - I can shrink the table and make the pavilion a little deeper and I think you would agree the overlay of the wire frame is closer.
The table is now the same
But I can not take the pavilion past 40.7 - and that fits with the greenish hue in the table reflection.

 

[Maxine]

Wow, Garry, that''s too cool!!!
the only diff. on the GIA cert is very tiny...they list the depth as 61.1 (3.42mm)

These new techniques are very interesting....................so with a good pic like that , you can tell a lot!

I think Garry has a lab full of Australian elves who work busily in the background preparing all the toys and diamonds for blessed Aussies. These are ones whom I think sit and make Garry''s models. This way Garry can stand at the counter looking all Cloonieish, selling jewelry and diamonds and playing on the forum. He and his Aussie elves work some amazing magic with these wire frame models.

 

[lostdog]

Well, I was off by only .4% on the LGF. And off massively on everything else. Still, a good thing to learn from.

Garry is The Man, though we already knew that.

These new techniques are very interesting....................so with a good pic like that , you can tell a lot!It is easier when the stone is perfectly symmetrical

Garry,

Symmetry isn''t everything. Take a look at this one.

Wow...what are the specs on that one?????

 

[denverappraiser]

I'll let the elves play with it for a bit before I spoil the fun but I'll just say that this baby has just about every defect that PSers are trained to look for except that the symmetry isn't too bad. That's what makes it difficult for this sort of task. It's way outside the norm.

By the way, it measures 6.07x6.23x4.15mm

While you were posting, Neil, i went to get my idealscope and pendant.......a very SIMILAR pattern.......With mine, there''s not a lot going for it by the numbers, but it''s a very pretty stone!!! I get comments on it all the time....and although it''s an H, it actually faces up quite well.....does that stone LOOK ok, too??? (if you look at mine right, you can actually see the setting underneath it!! but even the appraiser said it looked nice...he would recommend a change from yellow to WG setting, though)

 

[Garry H (Cut Nut)]

Neil I suspect that is a CZ - in which case I can model it because DiamCalc has a cZ option and seettings for any Refractive Index.
But i think I know its heritage and proportions

Nope, it's a diamond
Yup, it's a doozy.

I had the blue part off of the ASET when I took this picture so the 30 degree obscuration shows as black.

Maxine
beautiful stone

are you thinking about buying it?

 

[Garry H (Cut Nut)]

Thne it is going to be hard to do Neil.

Have you tried removing the lens and shoting thru the small hole?
