1. What is the Diamond Value Calculator GIA?

The Diamond Value Calculator GIA estimates diamond market value based on GIA grading standards, considering carat weight, color, clarity, and cut quality. It provides a comprehensive valuation using industry-standard pricing factors.

2. How Does the Calculator Work?

The calculator uses the diamond valuation formula:

\[ Value = Carat \times \text{Price per carat} + \text{Adjustments for 4Cs} \]

Where:

$ Carat $ — Diamond weight in carats
$ Price per carat $ — Base price per carat in USD
$ Color factor $ — Multiplier based on color grade (D-J)
$ Clarity factor $ — Multiplier based on clarity grade (FL-I3)
$ Cut factor $ — Multiplier based on cut quality (Excellent-Poor)

Explanation: The equation accounts for the fundamental relationship between carat weight and price, with adjustments for the other three Cs (color, clarity, cut) that significantly impact diamond value.

3. Importance of Diamond Valuation

Details: Accurate diamond valuation is crucial for insurance purposes, resale value assessment, investment decisions, and ensuring fair market pricing in diamond transactions.

4. Using the Calculator

Tips: Enter carat weight (0.01+), base price per carat, and select appropriate GIA grades for color, clarity, and cut. All values must be valid positive numbers.
