Diamond Worth Calculator

Determining the real worth of a diamond requires more than just knowing its carat weight. Professional diamond valuation depends on multiple grading factors, market demand, and finishing quality. Our Diamond Worth Calculator is designed to combine all these essential elements into one powerful and easy-to-use tool.

Whether you are planning to sell your diamond, insure it, evaluate an investment, or simply understand its market value, this calculator provides a structured and detailed estimate in seconds.

The tool delivers:

  • Estimated Diamond Worth
  • Base Price Per Carat
  • Adjusted Price Per Carat
  • Overall Quality Multiplier

This breakdown helps you understand not only the final value but also how each factor contributes to pricing.

What Makes This Diamond Worth Calculator Different?

Unlike basic diamond price tools, this calculator goes beyond the standard 4Cs. It incorporates:

  • Carat weight
  • Clarity rating
  • Color rating
  • Cut quality
  • Shape
  • Polish
  • Symmetry
  • Certification
  • Market condition

By including polish, symmetry, and current market demand, the tool provides a more advanced and realistic valuation estimate.

How the Diamond Worth Is Calculated

The calculator uses a structured formula to determine value step by step.

Step 1: Base Price Per Carat

The clarity rating determines the base price per carat. Higher clarity grades such as FL or IF command significantly higher base pricing than SI or I grades.

Step 2: Quality Multiplier

A quality multiplier is calculated using:

  • Color rating
  • Cut quality
  • Shape
  • Polish
  • Symmetry
  • Certification
  • Market condition

All these factors are multiplied together to create a combined quality score.

Step 3: Adjusted Price Per Carat

Adjusted Price Per Carat = Base Price Per Carat × Quality Multiplier

This reflects how premium characteristics increase the diamond’s value.

Step 4: Total Diamond Worth

Total Worth = Carat Weight × Adjusted Price Per Carat

The result is a complete estimate of the diamond’s market value.

How to Use the Diamond Worth Calculator

Using the tool is quick and straightforward.

Step 1: Enter Carat Weight

Input the diamond’s weight (for example, 0.90, 1.50, or 3.00 carats).

Step 2: Select Clarity

Choose from:

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

Higher clarity means fewer inclusions and stronger value.

Step 3: Choose Color Grade

Select from D (colorless) to N. Diamonds closer to D are typically more valuable.

Step 4: Select Cut Quality

Choose Ideal, Excellent, Very Good, Good, Fair, or Poor. Cut strongly impacts brilliance and desirability.

Step 5: Choose Shape

Options include:

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

Round Brilliant generally carries premium demand.

Step 6: Select Polish

Polish refers to surface finishing quality. Excellent polish improves light performance and value.

Step 7: Select Symmetry

Symmetry affects how evenly the diamond reflects light. Higher symmetry typically increases value.

Step 8: Select Certification

Certification options include major grading labs and uncertified stones. Certified diamonds generally hold higher resale value.

Step 9: Choose Market Condition

Select High Demand, Average Demand, or Low Demand. Market trends directly influence diamond pricing.

Step 10: Click Calculate

The calculator instantly provides:

  • Estimated total worth
  • Base price per carat
  • Adjusted price per carat
  • Quality multiplier

Example Diamond Worth Calculation

Imagine you have:

  • 1.50 carat diamond
  • VS1 clarity
  • G color
  • Excellent cut
  • Round Brilliant shape
  • Excellent polish and symmetry
  • GIA certification
  • High market demand

The calculator will:

  1. Use the VS1 clarity as the base price per carat
  2. Multiply color, cut, shape, polish, symmetry, certification, and demand
  3. Adjust the per-carat value
  4. Multiply by 1.50 carats

In seconds, you receive a detailed valuation breakdown without manual calculations.
