1. What is the Diamond Weight Formula?

The diamond weight formula estimates the carat weight of a loose diamond based on its dimensions (length, width, depth) and a shape-specific factor. For round diamonds, the typical factor is approximately 0.0059.

2. How Does the Calculator Work?

The calculator uses the diamond weight formula:

Where:

• \( Length \) — Diamond length in millimeters (mm)
• \( Width \) — Diamond width in millimeters (mm)
• \( Depth \) — Diamond depth in millimeters (mm)
• \( Factor \) — Shape-specific constant (typically 0.0059 for round diamonds)

Explanation: The formula approximates the volume of the diamond and converts it to carat weight using the shape factor.

3. Importance of Diamond Weight Calculation

Details: Accurate diamond weight estimation is crucial for valuation, pricing, and certification purposes in the jewelry industry.

4. Using the Calculator

Tips: Enter all dimensions in millimeters and the appropriate shape factor. For round diamonds, use factor 0.0059. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical factor for round diamonds?
A: The standard factor for round brilliant cut diamonds is approximately 0.0059.

Q2: How accurate is this calculation?
A: This provides an estimate. For exact weight, the diamond should be weighed on a precision scale.

Q3: Does this work for fancy shapes?
A: Yes, but you need to use the appropriate factor for each shape (oval, princess, emerald, etc.).

Q4: Why measure in millimeters?
A: Diamond dimensions are typically measured in millimeters in the jewelry industry for precision.

Q5: What's the relationship between carats and grams?
A: 1 carat equals 0.2 grams (200 milligrams). The calculator shows weight in carats.
