Formula Used

The diamond value is calculated using the following formula:

Diamond Value = (Carat Weight × Base Price per Carat) × (Clarity Multiplier × Color Multiplier × Cut Multiplier)

The base price per carat is determined by industry averages. The multipliers adjust the value based on the diamond's characteristics:

Clarity: IF (30%), VVS1 (15%), VS1 (10%), SI1 (5%), I1 (0%)
Color: D (20%), E (15%), F (10%), G (5%), H (0%)
Cut: Excellent (20%), Very Good (10%), Good (0%)

For example, a 1.5 carat diamond with VS1 clarity, F color, and Very Good cut would have a value calculated as:

(1.5 × $2,000) × (1.10 × 1.10 × 1.10) = $3,630

Worked Example

Let's calculate the value of a 2.0 carat diamond with the following characteristics:

Clarity: VVS1
Color: D
Cut: Excellent

Using the formula:

(2.0 × $2,000) × (1.15 × 1.20 × 1.20) = $6,048

This means a 2.0 carat diamond with VVS1 clarity, D color, and Excellent cut would be worth approximately $6,048 based on current market averages.
