1. What is Diamond Carat Weight?

Carat weight is a measurement of a diamond's weight, where one carat equals 200 milligrams. It's one of the "Four Cs" used to determine a diamond's value, along with cut, color, and clarity.

2. How Does the Calculator Work?

The calculator uses the diamond carat weight formula:

Where:

• \( Diameter \) — Diamond's diameter in millimeters
• \( Depth \) — Diamond's depth in millimeters
• \( Factor \) — Shape-specific factor (typically 0.0061 for round diamonds)
• \( Adjustment \) — Adjustment factor (typically 1)

Explanation: The formula calculates the approximate weight based on the diamond's physical dimensions and shape characteristics.

3. Importance of Carat Weight Calculation

Details: Knowing a diamond's carat weight helps in valuation, insurance, and comparison shopping. It's especially useful when precise weighing isn't possible.

4. Using the Calculator

Tips: Measure diameter and depth in millimeters using precise calipers. For round diamonds, use factor 0.0061. For other shapes, consult a gemological reference for appropriate factors.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides an estimate. Actual weight may vary by ±3% due to cut proportions and measurement precision.

Q2: What's the factor for other diamond shapes?
A: Oval: ~0.0062, Princess: ~0.0083, Emerald: ~0.0080. Consult a gemologist for exact factors.

Q3: Does carat weight equal size?
A: Not exactly. Two diamonds of equal carat weight can appear different sizes based on cut proportions.

Q4: Why measure in millimeters?
A: Millimeters provide the precision needed for accurate carat estimation.

Q5: Can I use this for other gemstones?
A: Different gems have different densities, so specific gravity must be considered for accurate conversion.
