Diamonds are one of the most valuable gemstones, and their size plays a crucial role in determining their worth. For jewelers, gemologists, and buyers alike, knowing the accurate size of a diamond is essential for pricing, trading, and appraising. While most people are familiar with the traditional carat weight measurement for diamonds, calculating the precise volume of a diamond can provide more in-depth insights into its physical properties.
The Diamond Size Calculator is an invaluable tool for accurately calculating the size or volume of a diamond based on its length, width, depth, and other constant factors. In this article, we will dive into the details of how the Diamond Size Calculator works, explain how to use it, and provide an example calculation. We will also offer additional information on diamond size, along with answers to 20 frequently asked questions (FAQs).
What is Diamond Size?
Diamond size is often confused with weight, but they are two different things. The size of a diamond refers to its volume or the amount of space it occupies, while the weight refers to the mass of the diamond, typically measured in carats. The Diamond Size (DS) can be calculated by determining the dimensions of the diamond and applying them in a mathematical formula.
The most common dimensions used to calculate diamond size are:
- Length (A): The longest side of the diamond.
- Width (D): The side of the diamond perpendicular to the length.
- Depth (C): The thickness or height of the diamond.
Additional factors, like factor B and factor E, are constants used in the formula to adjust for the diamond’s cut and other characteristics.
How the Diamond Size Calculator Works
The Diamond Size Calculator uses a mathematical formula to calculate the volume (size) of a diamond. The formula used is:
Diamond Size (DS) = (Length × Width × Depth) / (Factor B × Factor E)
Where:
- Length is the longest side of the diamond (measured in millimeters).
- Width is the side perpendicular to the length (measured in millimeters).
- Depth is the thickness of the diamond (measured in millimeters).
- Factor B is a constant factor used to account for specific characteristics of the diamond’s cut.
- Factor E is another constant factor used in the calculation to fine-tune the size calculation.
This formula gives the Diamond Size in cubic millimeters (mm³), providing an accurate volume of the diamond.
How to Use the Diamond Size Calculator
Using the Diamond Size Calculator is easy and straightforward. Here’s a step-by-step guide on how to use the tool to calculate the size of a diamond:
Step 1: Input the Length of the Diamond
Enter the length of the diamond (A) in millimeters. This is the longest side of the diamond. Make sure to measure it accurately using a ruler or caliper.
Step 2: Input the Width of the Diamond
Enter the width of the diamond (D) in millimeters. This measurement is perpendicular to the length and is also crucial in determining the diamond’s volume.
Step 3: Input the Depth of the Diamond
Next, enter the depth (C) of the diamond in millimeters. The depth is the height of the diamond, from the flat table to the tip of the pavilion (the bottom).
Step 4: Input Constant Factor B
Enter the constant factor B. This factor is typically based on the diamond’s specific cut or other adjustments made by the jeweler or gemologist.
Step 5: Input Constant Factor E
Enter the constant factor E. Like factor B, this constant adjusts the formula based on the characteristics of the diamond’s cut and shape.
Step 6: Click Calculate
Once you’ve entered all the required values, click the “Calculate” button. The tool will use the formula to calculate the Diamond Size and display the result in cubic millimeters (mm³).
Example: How to Use the Diamond Size Calculator
Let’s walk through an example to see how the Diamond Size Calculator works in practice:
Scenario:
You have a diamond with the following measurements:
- Length (A) = 6.5 mm
- Width (D) = 6.2 mm
- Depth (C) = 4.0 mm
- Factor B = 1.2 (a constant based on the cut of the diamond)
- Factor E = 1.5 (another constant based on diamond shape and characteristics)
Step 1: Input the values into the calculator:
- Length = 6.5 mm
- Width = 6.2 mm
- Depth = 4.0 mm
- Factor B = 1.2
- Factor E = 1.5
Step 2: Apply the Formula
Diamond Size (DS) = (6.5 × 6.2 × 4.0) / (1.2 × 1.5)
Step 3: Calculate
Diamond Size (DS) = (161.6) / (1.8)
Diamond Size (DS) = 89.78 mm³
Step 4: View the Result
The Diamond Size is 89.78 mm³.
This means the diamond has a volume of 89.78 cubic millimeters.
Why Use the Diamond Size Calculator?
The Diamond Size Calculator offers several advantages:

Helpful Information: Things to Keep in Mind
1. Factors Affecting Diamond Size
The size of a diamond can be influenced by several factors beyond just its dimensions. The diamond’s cut and shape can affect how its size is perceived. A well-cut diamond may appear larger than a poorly cut one, even if their dimensions are the same.
2. Diamond Carat Weight vs. Size
While carat weight is a common measure of diamond size, it does not directly measure the diamond’s volume. The Diamond Size Calculator gives a more accurate understanding of the diamond’s actual volume in cubic millimeters.
3. Diamond Cut Proportions
The calculator requires constant factors (B and E) based on the diamond’s cut proportions. These constants are typically provided by professional gemologists and can vary depending on the shape and cutting style of the diamond.
4. Adjusting for Specific Cuts
Different diamond shapes (round, oval, princess, etc.) may require different constant factors for accurate size calculations. Always ensure that the correct factors are used for the specific diamond being evaluated.
