This is a very beautiful piece! The way the triangles nestle next to the princess cut is an interesting design. However, in this one case, I think I'd want the accent stones out away from the princess cut just a little so that they weren't slightly underneath it and obscured a bit in a face up view. I would also want them with their tables parallel to the table of the princess cut so that all showed face up at the same viewing angle. Maybe a bar of metal to the side of the princess cut on each side and then a reorientation of the side stones. Makes the whole presentation a bit wider, which could be good or bad, I guess.
But I can also see the virtues of how you've done it. I notice this is an incredibly long thread, which speaks to the volume and richness of your body of work. I think this is the first time I've actually had any criticism, which just goes to show that a flea can see farther when standing on the head of a giant, I guess. Finally...maybe...LOL.
Keep 'em comin' You da man!
