How Much is a 4 Carat Diamond? Complete 2025 Price Guide

The 4 Carat Diamond Price Spectrum: $15,000 to $500,000+

Let's cut straight to the numbers. A 4 carat diamond can range from approximately $15,000 to over $500,000, depending on the four critical factors that determine diamond value. This isn't just price variation—it's the difference between a decent stone and a museum-quality masterpiece.

The Four Factors That Control Your Investment

1. Cut Quality: The Performance Engine

The cut is your diamond's performance engine. A perfectly cut 4 carat diamond will outperform a poorly cut 5 carat stone every time. For maximum impact, insist on Excellent or Ideal cut grades.

• Round Brilliant (Most Popular): $25,000 - $400,000
• Princess Cut: $20,000 - $320,000
• Emerald Cut: $18,000 - $280,000
• Oval Cut: $22,000 - $350,000

2. Color Grade: The Purity Factor

Color grade dramatically impacts both price and visual appeal. Here's how color affects your 4 carat investment:

• D-E (Colorless): Premium pricing, museum quality
• F-G (Near Colorless): Excellent value, undetectable tint
• H-I (Near Colorless): Smart budget choice, minimal warmth
• J-K (Faint Yellow): Budget option with noticeable warmth

3. Clarity Grade: The Transparency Test

At 4 carats, clarity becomes critical. Inclusions that are invisible in smaller stones become obvious in larger diamonds:

• FL-IF (Flawless): $200,000+ (Investment grade)
• VVS1-VVS2: $100,000 - $300,000 (Premium choice)
• VS1-VS2: $60,000 - $150,000 (Excellent value)
• SI1-SI2: $25,000 - $80,000 (Smart budget option)

Lab-Grown vs Natural: The Value Revolution

The game has changed. Lab-grown 4 carat diamonds offer identical beauty at 60-80% less cost. Here's the comparison:
