Princess Cut Formula:
From: | To: |
The princess cut diamond weight formula estimates the carat weight of a princess cut diamond based on its length, width, and depth measurements. This calculation is essential for jewelers and diamond buyers to estimate weight when precise measurements are available but direct weighing isn't possible.
The calculator uses the princess cut formula:
Where:
Explanation: The formula accounts for the unique proportions of princess cut diamonds, which are square or rectangular modified brilliant cuts.
Details: Accurate weight estimation is crucial for diamond valuation, setting appropriate prices, and comparing diamonds of similar size. Carat weight significantly impacts a diamond's value.
Tips: Enter precise measurements in millimeters for length, width, and depth. Measurements should be taken with professional calipers for best results. All values must be positive numbers.
Q1: How accurate is this formula?
A: The formula provides a good estimate but may vary ±2-3% from actual weight due to variations in diamond proportions and cut quality.
Q2: Does this work for other diamond shapes?
A: No, this specific formula is only for princess cut diamonds. Other shapes have different conversion factors.
Q3: Why is the conversion factor 0.008?
A: This factor accounts for the average density and proportions specific to princess cut diamonds.
Q4: Should I use this instead of actual weighing?
A: This is for estimation only. Professional grading always uses precise scales for certification.
Q5: How do measurements affect the weight?
A: Deeper diamonds will weigh more for the same length and width, while shallower diamonds will weigh less.
