Middle of process!

Four main and corner (C1 only) step facets on crown, two steps (P1-P2) on pavilion.

A view into the Diamond via the pavilion....

table is going to come out smaller than 35 with even steps in the side view.
~31.8%
longer c3 in top view.

Go for two crown steps instead of three...

C1 45, C2 35-32 range.... should be good too!
C1 100%--- C2 50%+/- of C1 (or even less...)

 

[strmrdr]

biggest problem is middle outer edge step goes dark.

cant without using the cut designer which has been giving me fits by crashing and I havent figured out the corner facets yet.

Do the above change (at the crown) and lower P1 to 50 deg....

Can you do it with the same corner deg. as main?

 

[strmrdr]

3c3p crown as above, 50p1 still dark.

 

[strmrdr]

49p1 acceptable once mounted except in a bezel.

 

[diagem]

So you think only C1-46 with P1-48 solves it virtually?
I am not too sure its the only solution in real life...

 

[strmrdr]

keeping that area with any light return at all was why a bunch of combos didnt work.

well being less picky is another solution, I like too design worse case.
Course there could be a cutting trick I wouldnt think of doing or cant do in DC.

Right now: C1 (only one facet) is at 48.2-47.5 approx.
P1 is at 54

No bad "dark" effect!!!

not without the cut designer and getting the corners in the first place is beyond me in it.
it wont let me do 2 seperate girdle operations it needs, or atleast I havent figured it out yet.
I could do it gemcad back when I was playing with it.

 

[strmrdr]

its there..... backlighting is masking it...
it will get worse as the other facets are added.

Cause based on the above image (of real life)..., I dont identify a problem with the edges..., on the contrary..., the stone looks mighty bright to me even now!

On the contrary..., its a reflection of P2 (which reaches the culet as P3 is non-existence as of yet)
Once I cut P3 into the pav. it should get even brighter!

 

[diagem]

And you see it only on the bottom side of the image..., (the side near the base of the image...)
I dont see it on the top side....

top is glared from the lights and backlighting so cant see it.
put your hand behind it blocking light from the pavilion and it will show.
or put a red paper/cloth behind it and see the red thru the facets.

I cant..., It is not in my hands at the moment...

Strmdr, Diagem


My advice is to postpone this work on 3 weeks. In April will available new version DC with more powerful and much more stabile Cutdesigner

 

[diagem]

Two step crown..., needs a little touch up though....., (not yet final!)

Thanks so much for allowing us to see the in-process photos, DiaGem! This is exciting!!!! That shape looks drool-worthy so far!

You can notice in the above picture (now enlarged) the saw marks on the table of the Diamond.
Those marks originated at the first stage when the rough crystal was sawed into two pieces...
