What Is the Diamond Color Chart and What It Means?

Have you achieved something recently? We all go through seasons that demand more of us. Sometimes, you deserve to celebrate your hard work and resilience with decadent jewelry. Let's say you've decided to shop online for a tasteful diamond ring or for that pair of diamond flower earrings you've been eyeballing for the last couple of weeks to celebrate your commitment to yourself and your journey. 

If you've never shopped for diamond jewelry before, all of the jewelry jargon could be hard to decipher. You know you'll want to choose a gem that shines brilliantly, but what do letters have to do with a jewelry's color? Let's decode some of the four C's so you have a better understanding of how to judge a diamond's color with a color chart (aka diamond color grading). 

A Brush-Up on the Four C's

Maybe you've heard of the four C's before; cut, clarity, carat weight, and color. Most people are aware of that short list of qualities that determine a diamond's value, but they may not know what each of those words means practically. How can you ensure a diamond has the correct color? Let's look at each of the four C's to brush up on their meaning. 


Diamonds are a product of the miraculous processes of nature. While these gems have inherent value on their own, high-quality craftsmanship matters when it comes to a diamond's cut. When a diamond receives an ideal cut, it can transmit light even more radiantly than before. One of the most noteworthy things to remember is that a diamond's cut influences its fire, brightness, and scintillation. 

These three terms describe the way a diamond's cut impacts the way it interacts with light. Even to the untrained and naked eye, cut is one of the easiest things to spot. 


If you're unfamiliar with this term, you may be thinking clarity refers to transparency. Instead, this term refers to the absence of inclusions and blemishes. Natural earth-mined diamonds are formed due to a chemical interaction between carbon, heat, and pressure. One characteristic of an authentic earth-mined stone is the presence of imperfections called 'inclusions.' A less included diamond is worth more, and a diamond with increased inclusions is less desirable. 

You can understand the worth of your diamond by understanding the scale used to determine the inclusion level in diamonds. Essentially, the scale lists diamonds from the low to high end like this: Included (I), Slightly Included (SI), Very Slightly Included (VS), Very, Very Slightly Included (VVS), Internally Flawless (IF), and Flawless (F).

Carat Weight 

You may have already known that a carat represents how much a diamond weighs. Essentially, one carat is equal to two hundred milligrams. Because carat weight is so crucial to a diamond's worth, carat weight is judged on a one-hundred-point scale for the most accuracy. When all other factors are the same, a diamond with a greater carat weight will be more valuable. 


It may seem counter-intuitive, but a diamond's color grading does not refer to how much of its color is visible but rather the lack thereof. A chemically pure and structurally flawless diamond has no color. When trained gemologists grade a diamond's color, they do so under controlled lighting and with ideal viewing conditions. 

They look to see if it falls in a normal color range. A higher color grade indicates a more valuable diamond. Let's take a closer look at what each color grade (which is really a letter grade) indicates.

  • Colorless: Colorless diamonds are the most valuable diamonds due to their lack of color. These diamonds are chemically pure and fall under a D-F grading range. This includes d-color, e-color, and f color diamonds.  
  • Near Colorless: As their name implies, near colorless diamonds are the closest thing to colorless. They have a nearly indiscernible color to the untrained eye. On the color grading scale, these diamonds fall in the range of g color diamond, h color diamond, I color diamonds and j color diamonds. 
  • Faint and Very Light: In smaller diamonds, a very light and faint color grade will appear colorless when installed in a setting. However, in larger diamonds, the color will still be discernible. On the grading scale, these diamonds are a K-R rating.
  • Light: A diamond with a light color grade indicates that the stone in question shows visible color, but not as dramatically as a fancy yellow diamond. On the color grading scale, this falls under the S-Z rating. 
  • Fancy Yellow: This color grade implies a diamond with a visible yellow tint. Though it may be excellent in cut, clarity, and carat weight, this color grade will diminish its value. It can range in yellow hues, including a light yellow to an almost orange in color.
