Example Calculation

Let’s take an example to understand how the calculator works:

Diamond Weight: 1.5 carats
Diamond Quality: 9 (Very Good)
Rate per Carat: $5,000
Tax/Fees: 5%

Step 1: Adjust Rate by Quality Factor
Quality factor = 9 / 10 = 0.9

Step 2: Calculate Gross Value
Gross Value = Weight × Rate × Quality Factor
= 1.5 × 5000 × 0.9
= $6,750

Step 3: Calculate Tax/Fees
Tax = Gross × Tax Percentage / 100
= 6,750 × 5 / 100
= $337.50

Step 4: Calculate Net Value
Net Value = Gross − Tax
= 6,750 − 337.50
= $6,412.50

So, after applying the quality adjustment and tax, the diamond’s net value is $6,412.50.
