4 C’s

When you ask yourself “how to choose a diamond?”, one of the most important things you need to know are a diamond’s 4 C’s. The 4 C’s are a universal method for evaluating a diamond’s quality. These are:

• Cut Grade: This refers to the cut quality and proportions of a diamond that are graded from Excellent to Poor. Diamonds with excellent cuts are desirable because they can best reflect light, which creates diamond’s signature sparkling appearance. Cut grades are only given to round diamonds, while fancy cut diamonds, like emeralds and cushions, do not have official cut grades.
• Clarity Grade: This grade denotes the amount of internal and external marks a diamond has, known as inclusions and blemishes respectively. Clarity grades range from FL to I3, with FL attributed to flawless diamonds and I3 to denote a visibly flawed diamond. To the naked eye, it’s not always easy to see imperfections, but when a diamond is examined under a loop imperfections can be seen.
• Carat Weight: This indicates how much a diamond weighs in carats, abbreviated to ct. A single carat weighs 0.2 grams.
• Color Grade: This refers to how much color a diamond displays on a scale from D to Z with D being colorless and Z a light yellow. The less color a white diamond displays, the greater its value. Keep in mind that fancy colored diamonds, such as fancy yellow and fancy blue, do not have letter grades, instead they are graded from Fancy Light to Fancy Vivid depending on the intensity of the diamond’s color

Much like any purchase, buying a diamond will require some level of compromise depending on how much you are looking to spend. You may choose, for example, to opt for a higher carat weight and a lower clarity grade in order to stay on budget. Or you may decide to go for a better color grade and a lesser cut grade. Understanding what each of the 4 C’s means will help you establish your priorities, what you are willing to compromise on and what you are not.

 

Shape

Diamonds can be cut into various shapes with round brilliant as the most popular cut and therefore typically more expensive. Any other diamond cut is known as a fancy cut, such as hearts, ovals and pears. The value of fancy cut diamonds fluctuates depending on market trends and popularity. Consider all diamond shapes in the image below and choose a diamond cut that best suits you or the person you are buying it for.

Which diamond shape is best for you?

• Round diamonds: a classic and timeless diamond shape. If you are looking for maximum sparkle in the stone, round diamonds are the best choice.
• Princess cut diamonds: the second most popular diamond shape, princess cuts are stylish and sophisticated.
• Oval cut diamonds: currently a very popular choice, oval diamonds are a soft, elegant shape.
• Emerald cut diamonds: this modern, geometric diamond shape is favored by many celebrities. It is important to choose an emerald cut with a strong clarity grade, as any imperfections in the stone are very apparent in this shape.
• Pear diamonds: this shape is great for anyone looking for a more individual, statement stone.
• Heart shaped diamonds: cut into the shape of a love heart, this cut is popular amongst those looking for a unique diamond.
• Radiant diamonds: this shape combines the modern elegance of the emerald cut with the brilliance and sparkle of the round diamond.

 

Polish

When a raw diamond is cut and polished, microscopic abrasions may occur. Polish refers to the smoothness of a diamond’s facets on a scale from Excellent to Poor.

 

Symmetry

This denotes how well aligned the facets of a diamond are, such as the diamond’s crown, girdle, culet and table. Symmetry grades range from Excellent to Poor.

 

Fluorescence

This refers to how greatly a diamond glows blue under ultraviolet light. These grades range from None to Very Strong fluorescence. Typically, the more fluorescence a diamond displays, the lower its value. The reason for this is that strong fluorescence can create a milky appearance to the stone.

 

Treatment

Diamonds may receive artificial treatments to improve its clarity or color, such as HPHT or fracture filling. However, treated diamonds are considered to be less valuable than natural diamonds. This is because they have been artificially improved and are therefore not as rare as naturally occurring diamonds of the same quality.

 

Certification

Diamond certificates are grading reports that detail a diamond’s quality, such as the 4 C’s, polish, symmetry and more. When a diamond certificate is issued from a reputable diamond-grading laboratory, such as the GIA, they are a great resource for understanding all of the characteristics of your diamond. A certificate is not the same thing as a jeweler’s appraisal or an insurance appraisal, these are typically a jeweler’s opinion rather than official grading’s issued by a diamond grading laboratory.

 

Setting

If you are planning on buying diamond jewelry such as an engagement ring, the setting can affect the appearance of the stone. For example, if your diamond has a bezel setting, only the table of the diamond will be visible, making it easier to hide imperfections on the stone. With the right setting you can mask imperfections on a diamond or illustrate its brilliance. A prong setting on the other hand, elevates the diamond and allows more light to pass through, perfect for emphasizing the beauty of your diamond.
