Cut Cornered Rectangular Step Cut...., Strmrdr???

[diagem]

Strmrdr..., ready for another exercise?

Any idea''s (as far as numbers) for a new monster?

You game?

 

[strmrdr]

rofl, just the other day I was playing with something like that in DC and thought of you.
I didnt have time then too play with it a whole lot.

 

[diagem]

25-27% crown height is a must for a monster..., no?

 

[strmrdr]

What lxw ratio do you want it makes a huge difference in the angles?
~45% table?

1:1.40 ratio..., table 40%

 

[strmrdr]

monster1

 

[strmrdr]

monster2
both 1.4 ,~30% table, depth is over 80....

 

[strmrdr]

personaly I like this shape, the return needs too be optimised but what do you think of the general shape?

 

[strmrdr]

1.85 H SI1 64.5% 58% GIA - no vg ex ft 8.38x6.03x3.89

8.4x6x5.1 84.9% depth.
1.80ct
If that don't demonstrate that depth means nothing with fancy step cuts
It does create a marketing issue however.

Im working up a 40% tabled crown, getting the crown right is the hardest part of the whole process once a workable crown is develped the rest is easy.

3c 3p so I dont have too use the cut designer.

 

[diagem]

Pool of water..., anyone up for a swim?

 

[mercoledi]

Oooh! Do we get to watch the whole process? That would be so cool!

 

[strmrdr]

Here is my proposed design taking into account the rough shape.

 

[tberube]

would you call that a rectangular asscher or a modified emerald cut?? Heehee....

Personally, I think that''s an awesome shape. How do you think it would fair on fire and light return, and all that good stuff?

 

[strmrdr]

We are going too lose some yeild with the high crown by the looks of the rough.
but this is a monster :}

angles:
T: 40%
ch: 27.2
td: 78.3
c:
50.9

32

P:
56.5
44.5
34.3

h1/h2 100%
h2/h3 110% <--- 100% works too

corner break: 19 degrees
corner break ratio 17%

 

[strmrdr]

ASET any of these is not going to be very bright but will be very fiery.
gettting any red at all in the aset is work.

 

[strmrdr]

little different and a bit more red in ASET
angles:
T: 40%
ch: 27.2
td: 80.8
c:
50.9
45
32


P:
56.5
48 <---- changed
34.3


h1/h2 100%
h2/h3 110% <--- 100% works too


corner break: 19 degrees
corner break ratio 17%

6mm x 8.4mm x 4.85 for 2.10ct
spread suffered a lot going from the 30% to 40% table but retained weight went up.

 

[diagem]

Storm...,try going back to the original shape...
The shape in subject needs a balance..., the straight edge at the length needs to be longer than the straight edge of the width...

Show me a P1-54, P2-41, P3-32 or 31 deg. on the mains...
P1-51, P2-39, P3-30 or 29 deg. on the corners...

 

[lovewhitediamonds]

Ooooo... I LOVE this! I want one!

Elongated Asscher?? The length of an EC with the facets of an asscher?! YUM!
But would the depth play a part in the light return? Just gorgeous!

 

[Nicrez]

Is there a name or brand for this cut?

I just recently saw it in the trade and wondered if it was just a modified emerald shape cut for retention of a specific rough, or cut to improve clarity...
