1. What is the Princess Cut Carat Formula?

The Princess Cut Carat Formula estimates the carat weight of a princess cut diamond from its dimensions (length, width, and depth in millimeters). This calculation is based on the standard density and shape characteristics of princess cut diamonds.

2. How Does the Calculator Work?

The calculator uses the Princess Cut formula:

Where:

• \( Length \) — Length of diamond in millimeters (mm)
• \( Width \) — Width of diamond in millimeters (mm)
• \( Depth \) — Depth of diamond in millimeters (mm)
• \( 0.0057 \) — Conversion factor for princess cut diamonds

Explanation: The formula accounts for the specific volume-to-weight ratio of princess cut diamonds, which have a square or rectangular shape with pointed corners.

3. Importance of Accurate Carat Calculation

Details: Accurate carat estimation is crucial for diamond valuation, comparison shopping, and understanding the relationship between physical size and weight.

4. Using the Calculator

Tips: Measure your diamond's length, width, and depth in millimeters using precise calipers. Enter all three dimensions for an accurate carat estimate.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate (±5%) for standard princess cut diamonds. Actual weight may vary based on exact proportions and cut quality.

Q2: Can I use this for other diamond shapes?
A: No, this formula is specific to princess cut diamonds. Other shapes have different conversion factors.

Q3: Why is depth important in the calculation?
A: Depth affects the diamond's volume, which directly relates to its weight. Deeper diamonds of the same length/width will weigh more.

Q4: What's the average size of a 1 carat princess cut?
A: Typically about 5.5mm × 5.5mm, but this varies based on depth and exact proportions.

Q5: Does this account for diamond density?
A: Yes, the 0.0057 factor includes the standard density of diamonds (3.52 g/cm³) adjusted for typical princess cut proportions.
