How to Buy a Diamond: The 4Cs Explained

Cut, color, clarity, and carat weight decide what a diamond looks like and what it costs. Here is how to weigh them against each other.

Cut is what makes a diamond sparkle. Learn how cut grades work, what proportions matter, and why cut deserves the biggest share of your budget.

Color grades run from D to Z, but the differences your eye can detect are much coarser. Match the color grade to the metal and save real money.

Clarity grades describe flaws under magnification. What matters is whether a stone looks clean to your naked eye, and that costs less than you think.

Carat measures weight, not how big a diamond looks. Learn how spread, shape, and buying just under the popular sizes stretch a budget.

Lab-grown diamonds are real diamonds at a fraction of the price. Natural diamonds hold tradition and scarcity. Here is how to choose with clear eyes.

Round, oval, princess, emerald, and beyond. Each shape has its own personality, sparkle pattern, and price per carat.

An independent grading report confirms what you are buying. Here is what the document covers, which labs to trust, and the lines worth reading twice.
