💎 Introduction: What Are the 4 Cs and Why Should You Care?

When shopping for a diamond, especially an engagement ring or a custom creation, you’ll often hear about the “4 Cs.” But what are they really—and which one matters most?

The 4 Cs—Cut, Color, Clarity, and Carat—form the global standard for diamond grading. At Bijouterie Jamil, we educate every client to ensure they’re confident, informed, and making a smart purchase.

Let’s break it all down in clear, practical terms so you can shop with total confidence.

1️⃣ Cut: The Sparkle Factor

Cut refers not to the diamond’s shape (like round or oval), but to how well its facets reflect light. A well-cut diamond will sparkle brilliantly, while a poorly cut one will look dull—even if it’s large.

Grades:

• Excellent

• Very Good

• Good

• Fair

• Poor

💡 Our Tip: Cut is the most important C. Prioritize it—even if it means compromising slightly on size or clarity.

2️⃣ Clarity: How Flawless Is It?

Clarity measures the number of inclusions (internal) and blemishes (external) visible under magnification. Most flaws are microscopic and don’t affect the diamond’s beauty to the naked eye.

Grades:

• FL (Flawless)

• IF (Internally Flawless)

• VVS1/VVS2 (Very Very Slightly Included)

• VS1/VS2

• SI1/SI2

• I1/I2/I3 (Visible inclusions)

💡 Our Tip: Go for VS1–SI1 clarity for great value without visible imperfections.

3️⃣ Color: The Whiter, the Better?

Diamond color is graded from D (colorless) to Z (light yellow or brown). The closer to D, the more rare (and expensive) the stone.

Color Grades:

• D–F: Colorless

• G–J: Near colorless

• K–M: Faint yellow

• N–Z: Noticeable color

💡 Our Tip: G–H color offers near-colorless beauty at a better price than D–F.

4️⃣ Carat: How Big Is It?

Carat refers to the weight of the diamond—not its size. Two diamonds can both be 1 carat but look different depending on their cut and shape.

💡 Our Tip: A well-cut 0.90ct diamond can appear nearly identical to 1ct but cost significantly less.

🎯 What Matters Most When Choosing a Diamond?

• Cut is king: It affects brilliance more than anything else.

• Clarity and color can be balanced depending on your taste and budget.

• Carat is about presence—but bigger doesn’t always mean better.
