Diamond Value Calculator

Understanding the true value of a diamond can feel overwhelming. With multiple grading factors affecting price, even small differences in quality can significantly impact market value. Our Diamond Value Calculator simplifies this process by giving you a fast, structured, and reliable value estimate based on professional diamond pricing factors.

Whether you are planning to sell a loose diamond, insure it, upgrade it, or simply evaluate its worth, this calculator provides an instant breakdown of:

  • Estimated Diamond Value
  • Price Per Carat
  • Overall Quality Rating

Instead of guessing or relying on rough averages, you can now generate a personalized estimate in seconds.

What Is the Diamond Value Calculator?

The Diamond Value Calculator is an advanced online estimation tool that calculates a diamond’s market value based on the most important pricing components:

  • Carat weight
  • Clarity grade
  • Color grade
  • Cut grade
  • Shape
  • Certification
  • Fluorescence

Each of these factors influences the final price per carat. The calculator combines them into a quality rating multiplier that adjusts the base clarity value and generates a customized valuation.

This structured method helps provide a realistic approximation of diamond pricing based on widely recognized grading principles.

How the Diamond Value Is Calculated

The calculator uses a multi-step valuation formula to ensure accuracy and transparency.

Step 1: Quality Rating Multiplier

The calculator first determines a Quality Rating using:

  • Color multiplier
  • Cut multiplier
  • Shape multiplier
  • Certification multiplier
  • Fluorescence multiplier

These factors are multiplied together to generate an overall quality score.

Step 2: Price Per Carat

Price Per Carat = Clarity Value × Quality Rating

Clarity serves as the base value because internal purity significantly affects diamond rarity and pricing.

Step 3: Total Diamond Value

Total Diamond Value = Carat Weight × Price Per Carat

This final step gives you the estimated overall diamond worth.

The result provides:

  • Estimated total value
  • Exact price per carat
  • Quality rating multiplier

How to Use the Diamond Value Calculator

Using the tool is simple and takes less than one minute.

Step 1: Enter Carat Weight

Input your diamond’s carat weight (for example, 0.75, 1.00, or 2.50).

Step 2: Select Clarity Grade

Choose from:

  • FL (Flawless)
  • IF (Internally Flawless)
  • VVS1 / VVS2
  • VS1 / VS2
  • SI1 / SI2
  • I1 / I2 / I3

Higher clarity means fewer inclusions and higher price per carat.

Step 3: Choose Color Grade

Select a grade from D (colorless) to N (visible tint). Diamonds closer to D are rarer and more valuable.

Step 4: Select Cut Grade

Choose from Ideal to Poor. Cut directly impacts brilliance and visual appeal.

Step 5: Choose Shape

Select the diamond shape:

  • Round Brilliant
  • Princess
  • Cushion
  • Oval
  • Emerald
  • Asscher
  • Radiant
  • Pear
  • Marquise
  • Heart

Round Brilliant typically carries the strongest demand in the market.

Step 6: Select Certification

Certification influences buyer confidence and resale value. Options include:

  • GIA Certified
  • AGS Certified
  • IGI Certified
  • EGL Certified
  • Other Certification
  • No Certification

Diamonds certified by respected laboratories generally command higher prices.

Step 7: Select Fluorescence Level

Fluorescence can slightly impact value depending on strength:

  • None
  • Faint
  • Medium
  • Strong
  • Very Strong

Step 8: Click “Calculate”

The calculator instantly displays your estimated diamond value and pricing breakdown.

Example Diamond Valuation

Let’s say you have:

  • 1.20 carat diamond
  • VS1 clarity
  • G color
  • Excellent cut
  • Round Brilliant shape
  • GIA certification
  • No fluorescence

The calculator will:

  1. Generate a quality rating multiplier
  2. Apply it to the clarity value
  3. Calculate price per carat
  4. Multiply by 1.20 carats

Within seconds, you receive a detailed estimate of your diamond’s worth.

Why Each Factor Matters in Diamond Pricing

Carat Weight

Larger diamonds are rarer and increase exponentially in price as size grows.

Clarity

Fewer inclusions mean higher rarity and stronger resale value.

Color

Colorless diamonds reflect light better and are generally more valuable.

Cut

Cut determines brilliance and sparkle. Even a high-carat diamond can look dull if poorly cut.

Shape

Market demand varies by shape. Round Brilliant often commands premium pricing.

Certification

Third-party grading adds trust, transparency, and liquidity in resale markets.

Fluorescence

In some diamonds, strong fluorescence may slightly reduce value, while faint fluorescence typically has minimal impact.
