Understanding the 4Cs of Diamonds
Cut, color, clarity, and carat — learn what the 4Cs really mean and how to balance them to find the best diamond for your budget.
Every diamond is graded by four characteristics known as the 4Cs: cut, color, clarity, and carat. Understanding them helps you compare stones with confidence and spend your budget where it matters most.
Cut is the most important. It measures how well a diamond's facets are proportioned to reflect light, and it is what gives a stone its sparkle. A well-cut diamond can look more brilliant than a larger, poorly cut one.
Color grades how colorless a diamond is, from icy white to faint warmth, while clarity measures tiny natural inclusions — most of which are invisible without magnification. In both cases, you can often choose a slightly lower grade that looks flawless to the eye and save meaningfully.
Carat measures weight, not size, so shape and cut affect how large a stone appears. The art is in balancing all four to suit your taste and budget. At möA, we walk you through the 4Cs so the diamond you choose feels like the perfect fit.
