This month's cut is another unusual stone in that it is a fairly symmetric 9 sided stone cut on a 96 index. It is an 9 sided round brilliant. I called it NONOHNO because a nonogon is a nine sided figure in geometry and when I saw the table on the diagram all I could say was OH NO. It just doesn't look quite right. The stone looks fine, its the diagram that looks weird. This one takes advantage of 96 and 9 both being divisible by 3. I use a mirror image symmetry of 3 and get 6 equal cuts with 3 nearly equal cuts in between. To the naked eye it is a symmetrical 9 sided stone.
It is simple to cut and should be classified as simple to cut. Happy cutting!
