What is 4C for diamonds?

Prior to the middle of the 20th century, diamonds could not be evaluated using any standard. Diamond 4C, the first widely recognized global standard for characterizing these stones, was developed by GIA. 

The four parameters that make up 4C are color, clarity, cut, and carat weight. They aid in assessing a diamond’s quality and determining its worth. Every consumer knows exactly what he is getting these days.


The term “cut” describes a diamond’s symmetrical facets, angles, and proportions. The stone’s overall aesthetic appeal and propensity to dazzle are both strongly impacted by all of these variables. 


A diamond’s color is measured by how colorless it is. They are rated by the GIA from D to Z, where D represents the most colorless and Z represents those with a pronounced brown or yellow hue. 


Clarity assesses the absence of inclusions and blemishes.


The last but not least factor is the grade of the carat. It’s not the size of the stone that matters, but rather the weight of a diamond. Every diamond is exceptional in its uniqueness and beauty due to each of the four Cs.
