i think the trillions are too small for that stone, i like the proportions of the traps better. Plus, i really think the shape flatter the center stone better as well.
I think they dwarf your asscher a bit, I think I like the proportions of the first ones better. But there's no right or wrong here, if you want a bold and blingy look they might work for you!
Trillions would be my choice, however, they would be bigger than those featured in the pic in the first post, with the side next to the Asscher slightly shorter than or equal length as the main stone.
The issue with large traps you posted most recently is that they are too wide. If they were the same length, but less deep, I actually think they would work fine.
Does anyone use the Golden Mean for determining side stone size? the sides being approx. 1/3 the width of the main stone??
Compositionally, in art, it provides the most pleasing ratio.
