Shape

DIAMOND SHAPE

Diamond shape is the most visual characteristic. It is the diamond’s outline and comes in many forms such as round cut, princess cut, cushion cut, etc.

CARAT

DIAMOND CARAT

Diamond carat is its weight and reflects the diamond’s size. The larger the diamond, the rarer and more valuable it becomes. Carat is the most visible C.

COLOR

DIAMOND COLOR

Graded on a scale from D to Z, diamond color is its degree of colorlessness or tint of yellow/brown. The more colorless, the rarer and higher the value of the diamond.

CLARITY

DIAMOND CLARITY

Diamond clarity is set by microscopic imperfections and growths found naturally within the diamond. Diamond clarity makes every diamond unique.

CUT

DIAMOND CUT

Description text goes Diamond cut is the angles and proportions of the diamond’s cutting and faceting. The cut grade represents the diamond’s sparkle. Well cut diamonds have maximum sparkle.

CERTIFICATION

DIAMOND CERTIFICATION

Diamond certification validates the characteristics of a diamond. A grading report provides diamond value transparency. GIA and IGI are the most prominent certification laboratories.

Beyond The 4 C’s

Once you’ve learned the 4 C’s (cut, carat, color and clarity) of diamonds, venture on to the advance topics to make the perfect diamond selection. Use With Clarity’s expert advice guides to understand the anatomy of a diamond so you can choose the right polish, symmetry, fluorescence, girdle, culet, table and depth. By understanding the nuances of each diamond attribute, you’ll maximize your diamond’s price budget for the highest value. Click below to start with diamond symmetry and go beyond.

Beyond The 4 C’s

Fluorescence

Fluorescence is graded based on the diamond’s appearance in Ultraviolet light. Due to trace minerals that occur in the diamond as it forms naturally, or within the lab, the diamond can emit a blue glow. While fluorescence does not affect the appearance of the diamond in daylight, it can impact the price of the diamond. Therefore, fluorescence needs to be carefully assessed especially when it comes to color and clarity.

Symmetry

Symmetry is how well the facets of the diamonds are cut in terms of their proportion and alignment with one another. Well cut diamonds will also have excellent symmetry grades, so this attribute generally goes hand in hand with the cut grade. The symmetry grade can be seen on the IGI or GIA certificate.

Polish

Diamond polish is how well the diamond facets are polished and how smooth and even the surfaces are. If there is roughness, unevenness or remnants of the rough diamond, the diamond gets a lower quality. Polish is another advanced C that feeds directly into the cut grade of the diamond. Generally diamonds that have an excellent cut grade will also have an excellent polish grade.

Culet

The culet is the bottom portion of the diamond which needs to be in the correct proportion of the diamond based on the shape of the diamond. The culet of the diamond determines the passage of light through the diamond and ultimately the sparkle of the diamond. If the culet of the diamond is not in the correct proportion, there is light leakage and this can detract from the sparkle of the diamond.

Measurements

The measurements of the diamond determines once again how well the diamond sparkles and how well the facts can show off the color and clarity of the diamond. A well proportioned diamond of the same size, may look better than the diamond that is larger but has less than ideal measurements. The proportions of the diamond can also make the gemstone look larger faceup and maximize the beauty of the diamond.
