S, I don''t know much about asschers. I get the last few windmills are too small and don''t like them, but of the photos in this form I like the look of the second photo. The first photo windmills seem to large for me and the corners are cut too much for my liking.
What, in your opinion, is the best windmill size? |

No one will aim for a plan that tight. Maybe a 1.55ct plan - a little bit of leeway helps in case there is a little variation in saw plane, and tother stuff that does nt go to plan http://images.google.com.au/images?hl=en&rls=GGLL,GGLL:2007-51,GGLL:en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=octahedra&spell=1

There isnt really an optimal size there is too small and ok. 24% is my favorite but rare. 20-22% is likely the zone I'd target if cutting them. 18% is one of the most common on the market 16% is very common and on the too small side 14% is just getting greedy to save weight and there are a whole lot of them out there. Most of the the PS list would likely fall into the 14%-18% for the ones that the rest of the numbers line up. Thats just another reason you cant buy using numbers on the cert. But the main thing is that given the right look any of these can make very pretty diamonds. Well 14% is really pushing it.... |

real world today it would likely be cut 16%-18% 16% would make a 1.55 plan. |

Storm, I like the two extremes. I like the 1.56, too because for some reason the proportions please me. It looks like a square emerald cut and I like the play along the edges of the diamond. (ETA: It looks like a completely different cut type than the 1.44.) I like the 1.44 too, because the light return seems really even and the proportions are pleasing. The others, meh.

They are all at 21.6% crown height. The angle combo for this one is interesting: c: 56 45 30 21.6 height P 46 41 34 43.2 depth t: 60% girdle 3.5% total depth: 68.3 corner break angle: 45 degrees. wire frame side view: crown looks better from the top there is some limits in DC that make it impossible too get perfect spacing.

Let see the virtual look... |

cant keep it under 70% with those numbers. Would come out around 72% or so.... I went with 46 instead of 50 on the pavilion too make the angle relationship right. |
|
|
|
|
Based on 56 c1 and 45 c2 you will get this effect..., try going a bit shallower...
|
|
|
|
|
See..., you are aligning yourself with numbers too..., just like the 1.50 carat magic number!!! Who said something is wrong with 72% td!!!! The beauty will definitely be there... |

had too bump the pavilion back up to 50 to get the light return back up.70.9% depth, 51.4% table CH 21.3.
c: 48 39 30 p: 50 41 34.9 This one would have pretty lousy yield... I''d question being able too sell it at a reasonable price which is why I went 60 in the other one.

|
|
yes but my design goal was high crown and 70% depth and under and reasonable yield. The 24% corners are already costing some weight so tried too keep some weight in the crown. And marketing over 70% can get rough pardon the pun :} |

Now..., make the pav 1 a bit shorter in lenght..., are the three pav steps evenly devided in size? |
|
|
|
|
Not if you are getting a drop dead gorgeous gem...., or better yet it shouldnt! |
|
|
|
|
from the top p1 and p3 are even and p2 is slighly smaller. Since AGS has specified bottom view thats usualy what I go with. Personaly I dont think they shouldnt have too be even cuz I can design better asschers when they arent :} |
|

|
|
Looking good... ![]() What are the Pav angles? they dont seem to have to much contrast/range between them? |
|
|

50 45 37 This is one of my early designs and I could do better today. When the new design tool comes out in the new DC im going too redo it and fix the uneven crown steps. |
