1. What is Diamond Carat Calculation?

The diamond carat calculation estimates the weight of a diamond in carats based on its diameter in millimeters. This formula provides a quick and accurate way to determine carat weight without direct weighing.

2. How Does the Calculator Work?

The calculator uses the diamond carat formula:

Where:

• \( Diameter \) — Diamond diameter in millimeters (mm)
• \( 0.006 \) — Conversion factor for mm² to carats

Explanation: The formula calculates the approximate carat weight by squaring the diameter and dividing by the standard conversion factor of 0.006.

3. Importance of Carat Estimation

Details: Accurate carat estimation is crucial for diamond valuation, jewelry design, and purchasing decisions. It helps determine the approximate weight when direct weighing isn't possible.

4. Using the Calculator

Tips: Enter the diamond diameter in millimeters. Ensure accurate measurement for precise carat estimation. The diameter should be measured across the widest part of the diamond.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this carat estimation?
A: This formula provides a good approximation for round brilliant cut diamonds. Accuracy may vary for other diamond shapes and cuts.

Q2: Can this be used for all diamond shapes?
A: The formula works best for round brilliant cuts. Other shapes like princess, oval, or emerald may require shape-specific formulas.

Q3: What is the conversion factor 0.006 based on?
A: The factor 0.006 is derived from the relationship between surface area and weight for standard round brilliant cut diamonds.

Q4: How does carat relate to diamond size?
A: Carat is a measure of weight, not physical size. However, there's a strong correlation between diameter and carat weight for well-proportioned diamonds.

Q5: Should this replace professional gemological assessment?
A: No, this calculator provides estimates. For precise valuation and certification, consult with professional gemologists using calibrated equipment.
