The 4C’s are the universal language of diamonds. They help you understand what makes a diamond sparkle, how it’s valued, and how to choose the perfect one. Here’s your quick and easy guide.

1. Cut – The Sparkle Maker

The cut is the most important of all the C’s. It determines how well a diamond reflects light, creating brilliance and fire.

• A well-cut diamond looks bright and lively

• Even a larger diamond won’t sparkle if the cut is poor

Tip: Always prioritize cut for the most sparkle.

2. Color – The Diamond’s Tone

Diamond color is graded from D (colorless) to Z (light yellow).

• Less color = more rare

• Colorless and near-colorless stones (D–I) appear bright and white

Sweet spot: G–I for beauty and value.

3. Clarity – Natural Marks Inside the Diamond

Clarity describes tiny internal features called inclusions.

• Graded from Flawless (FL) to Included (I)

• Most inclusions are too small to see without magnification

Best value: VS1–SI1 for an eye-clean appearance.

4. Carat – Weight & Presence

Carat measures a diamond’s weight, not just its size.

• Larger carats cost more due to rarity

• Shape and cut also affect how big the diamond appears

Pro tip: A brilliant cut can make a diamond look bigger than its carat weight.

Final Sparkle Guide

The 4C’s work together to shape a diamond’s beauty and value. The perfect diamond is the one that matches your style, sparkle preference, and budget.
