I evaluated a diamond in the Holloway Cut Advisor and it came out as follows:
60.8% depth, 56% table, 34.7° crown angle, 40.5° pavilion angle
The result is for a symmetrical diamond with a medium girdle and very good polish
Light Return Excellent
Fire Excellent
Scintillation Excellent
Spread
or diameter for weight Very Good
Total Visual Performance 0.5 - Excellent - within TIC range
This stone was also evaluated with a Brillancescope, where it scored
White light: VH1
Colored Light: VH3
Scintillation: H2
Not bad, but significantly lower scores than many other stones on the Brillancescope which received inferior HCA ratings
So, which rating is to be believed...BrillanceScope, or HCA?
