The 4 Cs of Diamonds: What Every Buyer Needs to Know Before Choosing Fine Jewelry

When shopping for a diamond tennis bracelet, necklace, or pair of studs, understanding the 4 Cs—Cut, Color, Clarity, and Carat—is essential. These four qualities determine the value, brilliance, and beauty of your diamond jewelry.

At Tennis Couture, we make the buying process simple. Whether you're looking for natural or lab-grown diamonds, here’s everything you need to know—explained clearly and professionally.

1. Cut: The Most Important C

A diamond’s cut determines how well it reflects light—how much it sparkles.

  • A perfectly cut diamond looks brighter, livelier, and more elegant.

  • Poorly cut stones, even with good clarity or color, appear dull.

  • All Tennis Couture diamonds are expertly cut to maximize brilliance and symmetry.

2. Color: The Art of Staying Clear

Diamonds range in color from D (colorless) to Z (light yellow or brown).

  • Colorless diamonds are the most sought after for their crisp, icy appearance, especially in white gold settings.

  • We focus on diamonds in the D–F range, which appear beautifully clear to the eye.

3. Clarity: Nature’s Fingerprint

Clarity refers to the presence of inclusions (internal flaws) and blemishes (surface marks).

  • Most diamonds have minor inclusions—but they should not affect appearance.

  • We use diamonds in the VS1–VVS2 range, where imperfections are invisible to the naked eye but help keep the price accessible.

4. Carat: Size and Presence

Carat measures the weight of the diamond—not just the size.

  • For tennis bracelets and necklaces, we talk about total carat weight (TCW)—the combined weight of all stones.

  • Our pieces range from delicate 2 ct designs to bold 14+ ct creations, all carefully balanced for uniformity and comfort.

Why the 4 Cs Matter Together

While each “C” is important, what truly matters is how they work in harmony. At Tennis Couture, we carefully select every diamond to meet aesthetic and structural excellence, whether you're buying a 3 ct lab-grown tennis bracelet or a 10 ct natural diamond necklace.

We don't just sell jewelry. We deliver accessible luxury—pieces that look as radiant as they feel, without the unnecessary markup.
