60:60 EFFECT

[curious]

Would a stone with a 60.8% table and 61% depth qualify as a 60:60
or does it need to be exact?

How does the 60/60 effect the brilliance of the stone????

There is a strange fallacy that if a diamond has proportions of 60% depth and 60% table then it will be a beautiful diamond. It’s a great idea, but it simply does not work.

Here are two extreme examples of bad proportion combinations. Both are 60:60.

The pavilion angles on these vary from 36 degrees to 45 degrees and this range of variance actually exists out there. Of them all only the very small range between 39.7 degree and 40.4 degree pavilion angles would be worthy of consideration.
