How to Use the Diamond Calculator

A Diamond Calculator is a tool that estimates the market value of a diamond based on the Four Cs: Carat, Cut, Color, and Clarity, along with the current base price per carat.

Whether you're buying, selling, or just curious about your diamond’s worth, this calculator provides a quick and educational way to estimate its value using simplified real-world metrics.

Step-by-Step Guide:

1. Enter the Carat Weight

Carat is the measure of how much a diamond weighs. Larger diamonds are generally more valuable. Enter the weight (e.g., 1.0 for a 1-carat diamond).

2. Select the Cut Grade

The cut influences how brilliant and sparkly the diamond appears. Choose from:

Excellent (most valuable)
Very Good
Good
Fair

Each selection slightly affects the value multiplier.

3. Select the Color Grade

Colorless diamonds are more valuable. Choose from:

D (Colorless)
E-F (Near Colorless)
G-H
I-J

The closer to colorless, the higher the value.

4. Select the Clarity Grade

Clarity measures the number of imperfections. Choose from:

FL/IF (Flawless)
VVS, VS, SI, and I (ranging from very slight to visible inclusions)

Higher clarity means higher value.

5. Enter Base Price per Carat

This is the starting market price per carat for an average diamond (e.g., 6000 USD). You can look this up based on current pricing guides or leave it at your default.

6. Click "Calculate Value"

The tool calculates your diamond’s estimated total value based on all inputs.

Example:

Carat: 1.2
Cut: Very Good
Color: G-H
Clarity: VS1
Base Price per Carat: $7000

Estimated Value: ~$7,182.00
