A diamond's shape is one of its most important defining characteristics. From the round brilliant diamond to the princess cut, we'll help you choose the shape that complements your style.
Graded on an alphabetical scale from D (colorless) to Z (light yellow), a diamond's color rating indicates the degree of yellowness in the stone. The most valuable diamond is completely colorless.
A diamond's clarity indicates the presence or absence of inclusions and blemishes within the stone. Gemologists determine a diamond's clarity by examining it under a magnifying lens.
The carat is the unit of measurement for a diamond's weight. Larger diamonds are rarer and more valuable than smaller ones when all other characteristics are of equal quality.
A high-quality cut and polish will result in a symmetrical, brilliant diamond that reflects maximum fire and sparkle.
A Diamond Grading Report includes all of the stone's defining characteristics and scores. Any loose diamond purchase should be accompanied by a certified report.
A loose diamond with fluorescence will emit a soft, bluish glow when placed under UV or ultraviolet light.
