I don''t believe that you get more of one thing than what you lose in other components of total light return. This can be objectively tested to be certain, but I have never had a live sample for measurement. Increasing fire may look excellent for some folks, but most people want a diamond to look like most other diamonds. By adding more dispersion, one changes the character of the appearance. While it may be good for some consumers, I''d predict most will not want such a change.

It may be a very good alternative choice for someone who wants their diamond to be "different", but for the conformist majority, this would be a very unusual choice.

They look like CZs, with the extra fire

Depending on the number and placement of the gratings they can be less 'artificial'.
Top normal
Bottom With Etchings
Right Diffused Light
Left Spot Lighting

Hey this is great.
Now diamonds with 20% depth can look ideal cut.

Imagine the yield.
