    A diamond’s size is referred to by its carat weight. A carat is a unit of measurement equal to 200 milligrams.

    One carat is divided into 100 points, so that a diamond of 50 points weighs 0.50 carats. All diamond ct. t.w. may vary by .05 carats.



    Diamonds found in nature range from colorless to slightly yellow to brown. The best color that you can choose is colorless.

    The color grading system uses letters in the alphabet ranging from D, for the most colorless, all the way to Z, for the most color.



    A Master Cutter cuts a diamond in a way that maximizes the light reflected, increasing the brilliance. So, the better the cut, or “make,” the better the sparkle.
