Diamond Education

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.

A poorly cut diamond with incongruous proportions looks dull and dark because it allows light to escape out the bottom and sides.

In short, a well cut diamond sparkles a lot because it reflects and refracts light better than one not cut as well. A good cut increases price.

Color

White diamonds are not all colorless. The spectrum ranges 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 to rare, totally colorless diamonds.

A colorless diamond can be graded D, E or F; near colorless, G, H, I or J. A white diamond’s beauty and value increase the more colorless it is.

Clarity

Natural diamonds are formed by tremendous heat and pressure deep within the earth. This process can result in “inclusions” and “blemishes.” These are simply fancy words for imperfections.

No diamond is perfect, but the closer it comes, the higher its value. Inclusions seldom affect a diamond’s beauty, although they do affect price.

Carat Weight

Carat Weight refers to size and weight. Larger diamonds are scarce, and therefore more valuable.

However, two diamonds with the same carat weight can vary greatly in value, depending on the color, clarity and most importantly, the 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, but identical cut.

It’s simply a matter of deciding what matters most to¬†you, size or quality, then finding the best combination of size, color and clarity to suit your budget.
