Radiant Facet Patterns, what does it mean?

[sparkleandfire]

I have noticed that on the grading certs for radiants they show a facet pattern. Why are some different and does it mean a better cut or more sparkle based on the cut pattern?

Radiant cut diamonds simply come in so many styles, and often these diagrams do not accurately represent the actual facet patterns. It is impossible to tell which is better and predict radiant diamonds' appearance based on the diagram and grading report.
