We breakdown industry terms and how to understand the color and clarity scales to help you make an informed decision.

Champagne diamonds naturally have a warm and cognac hue. Their color varies on the amount of nitrogen stored in the stone during the diamond formation process. The higher the nitrogen content the more intense the champagne color will be.

Champagne diamonds rate a 10 on the Mohs scale of hardness, making them a great choice for everyday wear.

Other names for champagne diamonds include fancy color, cognac, and chocolate, which have orange or red undertones. They can be lighter in color and have a more yellow undertone. The terms Chocolate, Champagne or Cognac are sometimes branded by specific mines as a way to showcase their colored diamonds. These diamonds along with fancy colored diamonds are a newer trend. Their grading system is still being developed and is a bit different than the grading system used for near colorless diamonds. Let's break down the most common way of categorizing these diamonds.

Champagne Rings

Champagne diamonds are more common than white or near colorless diamonds and are considered less rare than other fancy colored diamonds. 

So if you take a similar near colorless diamond of the same carat weight and compare it to a champagne diamond the white diamond would typically have a more expensive price per carat. But that’s not to say that there’s not more or less rare champagne diamonds. Typically the more intense the color, paired with the carat weight and its clarity can significantly increase its rarity and thus its price. 

One of the most productive fancy color and champagne diamond mines is the Argyle Mine in Australia. The Argyle Mine really coined the terms cognac and champagne diamonds and its own color grading scale which is commonly used to denote the intensity of the color in each diamond.

While the GIA grading system is the most commonly used for white diamonds, the Argyle Mine system is the most commonly used for champagne diamonds.


The Champagne Color Grading ranges from light champagne to cognac, which would be considered the darkest and most intense saturation of color. 
  • Light Champagne: C1-C2 ~ N-R / S-Z on the GIA Color Scale
  • Medium Champagne: C3-C4
  • Dark Champagne: C5-C6
  • Cognac: C7
C1-C2 typically corresponds to the GIA color scale used for white or near colorless diamonds and would be in the same range as a color grade of N-R, very light yellow, or S-Z, light yellow. Beyond C-3 to C-7 these diamonds are much too saturated to be graded with an equivalency to the D-Z GIA color grading system. 

Champagne Color Range

Luckily since the color of champagne diamonds is the main difference between them and near colorless diamonds they are able to share the same clarity grading system.

So just like white diamonds, champagne diamonds are based on the presence of  internal inclusions or surface blemishes and then rated from IF - I2.

There are a few factors that go into the clarity grade, the most notable being the size and placement of the inclusions or blemishes. It's considered to be more rare the closer the clarity grade is to internally flawless.
