Diamonds.  Nature's Brilliance... Defined

At Bourghol Brothers Jewelers, we offer a full range of diamonds in all shapes, sizes and qualities.  All of our diamonds are hand selected and screened by our 3 G.I.A. Graduate Gemologists, providing our clients with the peace of mind that the diamonds you purchase are of the highest industry standard.  

Below you will find a brief description of the 4 C's of diamond grading, and we invite you to come in and see what sets our diamonds apart from the rest.

CARAT is the unit of measure used to describe the weight of any diamond or gemstone.

When a gemstone weighs less than 1 carat, it is then measured in points.  There are 100 points in 1 carat; 75 points in 3/4 carat; 50 points in 1/2 carat, etc.

If all other factors of a gem are equal, the more a diamond weighs, the more valuable the diamond will be.


The CUT of a diamond is the overall shape, proportions and finish of a polished diamond, ranging from Excellent to Poor.

Shape - dictates the overall look of the diamond (i.e. - Round, Princess, Emerald Cut, etc.)

Proportion - is the size and angle relationship that the diamond has been faceted to.

Finish - is the quality of the polish and facet placement of the diamond.

All of these factors affect the optical beauty of the diamond.  The finer the cut of the diamond, the more valuable the diamond will be.


CLARITY refers to the position of a diamond on a scale that ranges from Flawless to Imperfect.

The clarity characteristics found in diamonds can be described by two categories; inclusions which are internal, and blemishes which are external.

When a diamond is graded, the number, size, position, type and color of the clarity characteristics are all taken as factors in determining the clarity grade.

Very few diamonds are flawless, so naturally the closer the diamond is to the flawless grade, the more valuable the diamond will be.


COLOR in a diamond, refers to how close the color of a particular diamond is to being colorless.  

Most diamonds will have at least a trace of yellow or brown body color.

With the exception of the natural fancy color diamonds (i.e. - pink, blue, intense yellow, red, purple, orange or green), the closer the diamond is to being colorless, the more valuable the diamond will be.
