How to Use This Calculator

Enter the Base Price per carat for the stone without fluorescence factored in.
Enter the Carat Weight and select the Fluorescence Grade: none, faint, medium, strong, or very strong.
Select the Color Grade (D through I) — fluorescence impact varies significantly by color.
Review the price adjustment percentage and Adjusted Value with fluorescence accounted for.
Use the result to negotiate purchase price for stones with strong fluorescence.

What each input means

Base Price/ct (no fluor.): Base price per carat without fluorescence consideration
