GIA Diamond Price Calculator

Buying or valuing diamonds requires understanding several factors that determine their price. The GIA Diamond Price Calculator helps you quickly estimate the value of a diamond based on carat weight, cut, color, clarity, shape, and fluorescence. This tool is perfect for jewelers, buyers, or anyone curious about diamond pricing.

What Determines a Diamond’s Price?

A diamond’s price is influenced by the 4Cs—Cut, Color, Clarity, and Carat—as defined by the Gemological Institute of America (GIA). Additionally, diamond shape and fluorescence also affect value.

  • Carat Weight: Larger diamonds are exponentially more expensive.
  • Cut Grade: The quality of the diamond’s cut affects brilliance.
  • Color Grade: Colorless diamonds are more valuable.
  • Clarity Grade: Diamonds with fewer inclusions are higher priced.
  • Shape: Round diamonds generally cost more than fancy shapes.
  • Fluorescence: Strong fluorescence may reduce the value slightly.

How to Use the GIA Diamond Price Calculator

  1. Enter Carat Weight – Input the diamond’s weight in carats.
  2. Select Cut Grade – Choose from Excellent, Very Good, Good, Fair, or Poor.
  3. Select Color Grade – Grades range from D (Colorless) to M (Faint).
  4. Select Clarity Grade – Choose from FL (Flawless) to I2 (Included).
  5. Select Diamond Shape – Round, Princess, Cushion, Emerald, Oval, Pear, Marquise, Radiant, or Asscher.
  6. Select Fluorescence – None, Faint, Medium, Strong, or Very Strong.
  7. Click Calculate – The tool shows:
    • Base Price per Carat
    • Total Diamond Price
    • Price Range (Low & High)
    • Quality Rating
  8. Reset – Clear all inputs to calculate another diamond.

Example Calculation

Suppose you have a diamond with:

  • Carat: 1.5
  • Cut: Excellent
  • Color: E
  • Clarity: VS1
  • Shape: Round
  • Fluorescence: Faint

Calculation Process:

  1. Base Price per Carat: $5000
  2. Multipliers applied:
    • Cut: 1.2
    • Color: 1.25
    • Clarity: 1.2
    • Shape: 1.15
    • Fluorescence: 0.98
    • Carat Multiplier: 1 + 1.5*0.5 = 1.75
  3. Price per Carat ≈ $5000 × 1.2 × 1.25 × 1.2 × 1.15 × 0.98 × 1.75 ≈ $24,000
  4. Total Price = 24,000 × 1.5 ≈ $36,000
  5. Price Range: $30,600 – $41,400
  6. Quality Rating: Excellent Quality

This is displayed instantly in the calculator without manual computation.
