Choosing The Diamond


You've probably heard about the 4Cs of a diamond, and you may even know that it stands for Cut, Colour, Clarity and Carat Weight. The 4Cs are the the factors one needs to evaluate when shopping for a diamond.  Every diamond is unique and we will assist in picking the right one for your special loved one.

Carat Weight

Diamonds are sold by the carat (shown as ct.), which is actually a unit of weight, though most think of a carat in terms of size. The word "carat" comes from the "carob" seed, the original unit of measure for diamond traders. Today, a carat is equal to exactly 0.2 grams (about the weight of a paper clip).


A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous.  Cut is graded as: EXCELLENT, VERY GOOD, GOOD, FAIR, POOR.


Diamond Color Actually Means Lack of Color. A diamond's color is graded in a laboratory against the GIA Color Scale which ranges from D to Z. Grades D-E-F are in the colorless range and are considered the rarest and most valuable. Grades G-H-I-J are in the near colorless range and only a trace amount of color is detectable.  A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value.


The clarity categories and grades are: Flawless category (FL) diamonds have no inclusions or blemishes visible under 10x magnification. Internally Flawless category (IF) diamonds have no inclusions visible under 10x magnification, only small blemishes on the diamond surface.
