Whether you’re buying, selling, insuring, or simply researching, this calculator helps you understand the fair market value of a diamond in seconds.
Below, we’ll explain how this tool works, how to use it step-by-step, and answer common questions people have about diamond valuation.
🛠️ What Is the Washington Diamond Calculator?
The Washington Diamond Calculator is a web-based tool designed to provide an accurate estimated value, quality rating, and insurance suggestion for diamonds based on five core inputs:
- Carat Weight
- Clarity
- Color
- Cut
- Shape
It calculates the base price per carat and then adjusts it using multipliers for quality and rarity. The result is an estimated current market value and a recommended insurance value.
✅ How to Use the Washington Diamond Calculator
Using the calculator is easy and takes less than a minute. Follow these steps:
Step 1: Input the Carat Weight
Enter the diamond’s carat weight. For example, a typical engagement ring might be around 1.0 carat, but this could range from 0.1 to 5+ carats.
Step 2: Select Clarity Grade
Choose the clarity from options like FL (Flawless), IF (Internally Flawless), all the way to I3 (Included 3).
Step 3: Choose the Color Grade
Select the diamond’s color grade from D (Colorless) to M (Faint Color). The less color, the more valuable the diamond.
Step 4: Pick the Cut Quality
Cut impacts sparkle. Choose from Excellent to Poor.
Step 5: Select the Shape
Shapes include Round, Princess, Cushion, Emerald, Oval, Pear, Heart, and more.
Step 6: Click “Calculate”
Hit the Calculate button, and the tool will display:
- Estimated Diamond Value
- Quality Rating (0–100)
- Market Assessment
- Recommended Insurance Value
💎 Example Calculation
Let’s walk through an example:
- Carat Weight: 1.5
- Clarity: VS1
- Color: G
- Cut: Excellent
- Shape: Round
Clicking Calculate would produce an output like:
- Estimated Value: $48,000
- Quality Rating: 84/100
- Market Assessment: Premium quality – above average market value
- Insurance Value: $62,400
This tells the user the diamond has high resale and insurance worth due to its premium attributes.

❓ Frequently Asked Questions (FAQs)
1. What is the most important factor in diamond pricing?
Carat weight often has the largest impact, but clarity, color, and cut all significantly affect pricing.

Yes. Round diamonds usually cost more than fancy shapes due to popularity and cutting waste.

VS2 to SI1 offers good value—visible inclusions are rare but prices remain reasonable.

To account for how color, clarity, cut, and shape adjust the base value.

The current version does not support export or PDF generation.

A combined score of clarity, color, and cut on a 100-point scale.
