The 4 C's of Diamonds

Read about the 4 C's and find your perfect diamond at Safa Jewelers.

Diamonds are the most sought-after jewels in the world. They are revered for their superior durability, intense brilliance and stunning aesthetic. Diamonds are a high fashion accessory, a smart investment, and a family heirloom connecting multiple generations. They are the enduring symbol of everlasting love and sacred vows sealed in marriage. With such an esteemed history and profound sentiment, a diamond truly is forever.

Shopping for a jewel that will delight today, and one day be a legacy, is no easy feat. But not to worry, with some education the process is manageable, and even enjoyable. The essential education required can be boiled down to the 4 C’s of diamonds. A diamond’s appearance is determined by the color, clarity, cut and carat. Let’s look at how these four elements comprise the enduring beauty of a stone. 

1. Clarity

The clarity of a diamond depends on the visibility of the stone’s flaws, or "inclusions”. These are minuscule mineral deposits and fractures in the rock. Although most imperfections are too small to see with the naked eye, you want your diamond to be flawless and clean. The scale for clarity goes from Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1 and VVS2), Very Slightly Included (VS1 and VS2), Slightly Included (SI1 and SI2), and Included (I1, I2, I3). This scale ranges based on how visible any blemishes and inclusions are to a skilled grader, from FL with no inclusions or blemishes to I1, I2, and I3 where they are obvious affecting transparency and brilliance. These diamonds are checked under a 10x magnification.

2. Color

This refers to the color of a white diamond, ranging from totally colorless to yellow. As with clarity, you have some breathing room here. A diamond's color is graded on a scale beginning at D (colorless) and ending at Z (canary yellow or brown tint). Color influences both the rarity of the diamond and the cost. 

3. Cut

Cut pertains to the quality with which the stone is cut and to its shape. Round, princess, oval, emerald, pear, marquise, radiant, asscher and cushion are the main diamond cut shapes. Round cut is a very popular engagement ring option. The princess (square) is the second most in-demand option, and a current popular trend. This is where personal style and sparkle come in.

The cut grade is significant. This determines how a diamond reflects light. The more light reflected by a stone, the brighter the brilliance. And after all, it’s that shimmering sparkle that makes a diamond the most desired gemstone in the world. Cut is a where you want to invest. To maximize brilliance and durability, get as close to excellent as your budget allows. A diamond’s fire, the interplay of brilliance and sparkle, intensifies greatly with the quality of the cut. You should be fine with a Good rating, but Very Good or Excellent is preferable.


The carat in the diamond world is the weight of the diamond on the ring. Most engagement rings average about one carat. Carat is the other characteristic where you should splurge.
