1. What is the Emerald Carat Weight Formula?

The emerald cut diamond carat weight formula estimates the weight of an emerald cut diamond based on its dimensions. This calculation is particularly useful for jewelers and gemologists when precise weighing isn't possible.

2. How Does the Calculator Work?

The calculator uses the emerald cut formula:

Where:

• \( Length \) — Length in millimeters (mm)
• \( Width \) — Width in millimeters (mm)
• \( Depth \) — Depth in millimeters (mm)
• \( 0.0080 \) — Constant factor for emerald cut diamonds

Explanation: The formula accounts for the rectangular shape and step-cut facets characteristic of emerald cut diamonds.

3. Importance of Accurate Carat Calculation

Details: Accurate carat weight estimation is crucial for diamond valuation, setting design, and jewelry manufacturing processes.

4. Using the Calculator

Tips: Enter dimensions in millimeters (mm) using caliper measurements. All values must be positive numbers. For best results, measure to the nearest 0.01mm.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this formula?
A: The formula provides a good estimate (typically within ±5%) but actual weight may vary based on exact proportions and density.

Q2: Does this work for other diamond cuts?
A: No, different cuts have different formulas. Round brilliants use a different constant factor (0.0061).

Q3: Why is the depth important?
A: Depth affects the diamond's volume, which directly correlates with weight. Deeper stones of the same length/width will be heavier.

Q4: What's the average size of a 1 carat emerald cut?
A: Approximately 6.5×5×3.5mm, but this varies based on proportions.

Q5: Can I use this for other gemstones?
A: Only if they have the same specific gravity as diamond (3.52). Other gems require different constants.
