Why cut asschers with small corners and windmills?

[Serg]

pattern depth=8

 

[strmrdr]

for the curious:
"Additional features in new version of DiamCalc include ETAS images (effective total angular size) which at a glance give a good indication of where a diamond can gather light that creates brightness and sparkle."

Serg, how would you rate the potential of that combo based on the ETAS image?

No..., I am fighting yield calculations!!!

fair enough.
based on yeild where do you need the pavilion too be and I will design a top for it.
It is a lot harder designing bottom up but I will give it a go.

Its even harder designing and calculating on the material itself....
It can even hurt sometimes...

I have nothing really to impart to this thread, but I just wanted to say that that diamond is gorgeous...and I love this thread!

 

[somethingshiny]

Holy Windmills, Batman!

very nice collaboration!!!!

How big is it? What did the CH and depth come out at?
WOW!

A bad picture of the profile..., hey what can I do..., photography is not my profession!

Dont worry about the picture quality iv became very good at looking past the image at the stone! :}

How big is it? What did the CH and depth come out at?
WOW!

The numbers are:

My measurements for TD= 75.7% OGI=76.6%
CH OGI=23.9%

I took an OGI report out..., but the # are a bit off from reality

..., I dont know why..., maybe because of movement while being scanned???
I had to retry a few times..., I guess because of the small table...
Table% OGI=27.1%

OGI sux for scanning all asschers, the crown height is the only thing it usually gets right is what I have found. Even sarin misses at times.
Which is another reason you cant buy asschers by the numbers.
Whats the lxw?

Another faceup...

Another faceup...

the small area of center light return actualy looks good in this stone.
Mainly because of the small table I think.
A little bigger would be perfect but WOW I love it :}

5.20x5.19x3.93mm. = 0.79 carats (small hey?

)

Here is a tilt (dont know the angle of tilt...)

yummy! but a static pic can never do this stone justice.
.79 isn''t what I consider small :}
I bet this stone looks well above its physical size.

How did the weight retention come out?

So storm..., what do you think of your design on live???

Did you notice the tiny mess-up? you should..., you have the eyes for it!
There are two errors due to what Paul said previously..., there is no absolute symmetry when you cut Diamonds compared to designing virtual ones ...., especially step-cuts...

Let see if you can notice at least one of them

!

where? I just see character features!
These are very twitchy when it comes to angles and I see some angle variation in P2 and in one P3 windmill facet that show up face up.
If you want to get totally insane levels the culet isn''t perfectly formed. LOL
If it was something on the crown it is very very very hard too pick up on pictures/by eye but the pavilion features show up strongly.

 

[strmrdr]

looking again I think I see what your refering too but I cant decide if its the picture or the stone.
The lower windmill facet width looks a little off in places?

I dont think anyone but me would notice the first things I listed so went back for a recheck.
lol

WOW!!!!!!!!!!!!!!!, I have told 3 people in person about it today and they were all like HUH?
I never thought Id see them get cut.
Thank you!!!!!!!!

I cant stop coming back too this thread and drooling over the pictures!!!!!
WOW!

Youre pretty good!!!

No..., the lower windmill facets are quite fine...
1st. ---Pav 3 has a tiny degree range between the north/south and west/east direction. When everything came into place on the final stage of the cutting..., I noticed the culet was not closing perfectly into a point..., so I had to cut to opposed pav 3 in order to close the culet...

2nd. ---Due to the fact that the table is so tiny..., when polishing C 3 (by the table)..., the holders of the diamond on the dop had to small of a surface to grab (due to a tiny table)..., and if you notice carefully..., the table junctions with C3 are a bit off balance!

But that is just for us perfectionists...

I did want too say that if that is the case the reason I looked over it is that no real asscher is perfect in that area so its not something I dwell on.

ah ok so it is the picture lol
I went back and forth on it.

awesome job cutting it!!!!!!!!!

So having cut one is it something that can be sold at a resonable price or is the weight retention too bad?

Depending on the sales numbers..., what do you think a Diamond like this can fetch?

This one example is a D-E, VS/VVS. (according to my humble grading...

)

Just found out the PS search engine wont go under 40% table lol
Internet pricing of well cut conventional asschers in the .75-.79 range is topping out per ct at:
D VVS2 $5564
D VS1 $5473
E VVS2 $5436
E VS1 $4973
........................
RA would be about 35%+ over that.
It would depend on what kind of volume one wanted too move.
For limited production and sold as a custom match RA
I think 20% over would be more reasonable.
Im not good at setting prices because I always want too give people the best deal over being money hungry.
If put in production Id like to see the p3 angle changed slightly.
