The word "carat" has a unique origin and is the weight of the diamond. In fact the origins of the word carat can be traced in multiple languages. In Arabic it is derived from the root word: qirat, which means "fruit of the carob tree," also "weight of 4 grains." It also has ancient Greek and Italian roots! When deciding on a diamond the carat weight is important. It's also important to note the difference between "carat" and "total carat weight".

This is one of the first things to consider. The cut is not to be confused with the shape. The cut grading is a grading on the excellence and attractiveness of the diamond's proportions, angles, polish, finish, scintillation, fire and brilliance! These components determine how well a diamond presents itself,

This determines the colorlessness or whiteness of the diamond. Diamond color grades from GIA (The Gemological Institute of America) range between D and Z. The most colorless stones being a D color, and the stones that have a yellow or yellowish brown tint would be a towards the Z end. Be sure to check your certificate or appraisal to determine the true diamond color. If in doubt, always consult a reputable gemologist.
