1. What is the Diamond Price Calculator GIA?

The Diamond Price Calculator GIA estimates the market value of diamonds based on carat weight, GIA grading, and current market prices. It provides a comprehensive assessment of diamond valuation using industry-standard pricing models.

2. How Does the Calculator Work?

The calculator uses the diamond pricing formula:

Where:

• \( Carat \) — Diamond weight in carats
• \( \$ / Carat \) — Price per carat based on GIA grade
• \( GIA grade \) — Diamond quality rating (Excellent, Very Good, Good, Fair)
• \( Adjustments \) — Additional price factors (cut, clarity, color adjustments)

Explanation: The equation accounts for the fundamental relationship between diamond weight, quality grade, and market pricing, with adjustments for specific diamond characteristics.

3. Importance of Diamond Price Calculation

Details: Accurate diamond price estimation is crucial for insurance purposes, resale valuation, investment decisions, and ensuring fair market transactions in the diamond industry.

4. Using the Calculator

Tips: Enter carat weight in carats, select GIA grade, input current price per carat in USD, and include any additional adjustments. All values must be valid (carat > 0, price per carat > 0).
