4C’s Diamond Guide

A diamond’s beauty, rarity, and price depend on the interplay of all the 4C’s: cut, clarity, carat, and color. The 4C’s are used throughout the world to classify the rarity of diamonds. Come see the 4C’s for yourself at McCary’s!

CUT

Refers to the angles and proportions of a diamond. Cut also refers to shape: round, square, pear, or heart. A round diamond is the most brilliant of all diamond shapes.

COLOR

Refers to the degree to which a diamond is colorless. Diamonds range in color from icy winter whites to warm summer whites.

CLARITY

Refers to the presence of flaws or "inclusions" in a diamond. An inclusion in the middle or top of a diamond could impact the dispersion of light, sometimes making the diamond less brilliant.

CARAT

Carat is a measure of weight not size. Cut and mounting can make a diamond appear larger (or smaller) than its actual weight.
