1. What is the Oval Diamond Weight Formula?

The oval diamond weight formula estimates the carat weight of an oval-shaped diamond based on its length, width, and depth measurements. This calculation helps jewelers and buyers understand the approximate weight of a diamond when direct weighing isn't possible.

2. How Does the Calculator Work?

The calculator uses the oval diamond weight formula:

Where:

• \( Length \) — Length of the diamond in millimeters
• \( Width \) — Width of the diamond in millimeters
• \( Depth \) — Depth of the diamond in millimeters
• 0.0062 — Conversion factor for oval diamonds

Explanation: The formula accounts for the oval shape's unique proportions and converts the volume measurement to carat weight.

3. Importance of Diamond Weight Calculation

Details: Accurate weight estimation is crucial for diamond valuation, setting design, and price comparison. While actual weight may vary slightly, this calculation provides a good approximation.

4. Using the Calculator

Tips: Enter precise measurements in millimeters for length, width, and depth. All values must be positive numbers. For best results, measure the diamond with calipers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: The formula provides an approximation within about 5-10% of the actual weight, depending on the diamond's specific proportions.

Q2: Does this work for other diamond shapes?
A: No, this specific formula is for oval diamonds only. Other shapes have different conversion factors.

Q3: Why is the depth measurement important?
A: Depth affects the diamond's volume, which directly correlates with its weight. Deeper diamonds will weigh more for the same length and width.

Q4: What's the typical length-to-width ratio for oval diamonds?
A: Most oval diamonds have a ratio between 1.3:1 and 1.7:1, with 1.5:1 being the most popular.

Q5: Can I use this for mounted diamonds?
A: It's best to measure unmounted diamonds. For mounted stones, measurements may be less accurate.
