All About Diamonds

Diamonds are unique. Each has its own qualities, it’s own “fingerprint.” Like a fingerprint, no two diamonds are exactly alike. But there is a universal method for assessing the quality of diamonds, called The Four Cs – Cut, Color, Clarity, and Carat Weight. Using this method, the experts at Jay F. Jeweler will help you find your perfect stone.

Cut

Cut

When a diamond is cut with the ideal proportions for its shape, it reflects more light out of the top, producing incredible fire and brilliance.

On the other hand, a poorly cut diamond with improper proportions looks dull and dark because it allows light to escape out the bottom and sides. A proper cut increases a diamond’s value.

Color

Color

White diamonds are not all colorless. They fall on a color spectrum, ranging from light yellow to totally colorless.

A lettering system from D to Z is used to identify the amount of color present in each diamond, with D awarded only totally colorless diamonds.

A colorless diamond can be graded D, E, or F; near colorless, G, H, I or J. The closer a white diamond is to being colorless, the rarer it is and the higher its value.

Clarity

Clarity

No diamond is perfect. The heat and pressure required to form them also create imperfections known as “inclusions” and “blemishes.” Inclusions seldom affect a diamond’s beauty; however, they do affect price.

Carat Weight

Carat

A diamond’s carat weight – what many people first consider when they shop for diamonds – refers to its size and weight.

Larger diamonds are scarce, and therefore more valuable. However, diamonds with the same carat weight can vary greatly in value, depending on color, clarity, and cut.

A half-carat diamond with high color and clarity ratings may cost more than a three-quarter carat diamond with lower color and clarity ratings, even though they may have an identical cut.

It’s simply a matter of deciding what matters most to you – size or quality – then finding the best combination of factors to suit your budget.
