Diamond Light Return Score Calculator

Estimate diamond light return, fire, scintillation and overall cut performance from table %, depth %, crown angle, pavilion angle, girdle, culet, polish and symmetry.

Light Return Scoring Fire And Scintillation Cut Proportion Analysis Finish Grade Impact

Advanced Light Return And Cut Performance Calculator

Enter the key proportions and finish grades from a round brilliant diamond report to see how close the stone sits to an ideal light-performance profile. The calculator converts deviations from ideal into numeric penalties, then turns those penalties into scores for light return, fire, scintillation and overall cut performance.

Diamond Light Return Score Calculator Inputs

Diamond Light Return Score Calculator uses Table Percentage, Depth Percentage, Crown Angle, Pavilion Angle, Girdle Thickness.

Diamond Light Return Score Calculator Formula or Method

  • FireScore = 100 − (a × CrownPenalty + b × TablePenalty + c × PavilionPenalty + d × DepthPenalty + FinishPenalties fire )
  • ScintillationScore = 100 − (e × PavilionPenalty + f × CrownPenalty + g × DepthPenalty + h × TablePenalty + FinishPenalties scint )
  • LightReturn = 100 − (CrownPenalty + PavilionPenalty + DepthPenalty + TablePenalty + GirdlePenalty + CuletPenalty + FinishPenalties)

Reading Diamond Light Return Score Calculator Results

The results include Light Return Score, Fire Score, Scintillation Score, Overall Cut Performance.

Alongside Diamond Light Return Score Calculator, use Diamond Cut Grade Proportion Calculator to check whether a round brilliant diamond’s proportions line up with GIA-style cut grades from Excellent to Poor using depth %, table %, crown angle.

For a different result from Diamond Light Return Score Calculator, Diamond Crown Angle Calculator can convert table percentage and crown height percentage into a diamond crown angle in degrees and radians using a GIA-style geometric formula.
