While nature determines a diamond’s clarity, carat weight and color, an expert cutter is required to unlock the fire with a perfectly proportioned cut. A diamond is cut and polished with an exact number of facets. It’s proportions are derived by mathematical calculation.

A well-cut diamond, regardless of its shape offers the greatest brilliance and value. Light will reflect from one facet to another dispersing through the stone.

Fancy color diamonds in well defined colors including red, pink, blue, green and canary yellow, are highly prized and particularly rare, but in traditional diamonds the best color is no color at all. These diamonds are graded starting at D for colorless diamonds and continuing through the alphabet to Z, for yellowish ones.

While many diamonds appear colorless, they may actually have subtle yellow -brown tones in color grades of M to P.

A carat is equivalent to one fifth of a gram (.007ounces) and is divided into 100 points. All other characteristics being equal, the larger the diamond, the more rare, the higher the price per carat.

For example, a two carat diamond will cost far more than twice the price of a one carat diamond of the same quality.

Clarity refers to the presence of absence of inclusion found in the diamond. The fewer and smaller the inclusions, the less likely they will interfere with the passage of light through the diamond. Grading for clarity ranges from Flawless to Imperfect.
