What Colour Grade is a Champagne Diamond?

What Colour Grade is a Champagne Diamond?

The first thing you need to know when it comes to colour grading is that diamonds are graded using the GIA scale, ranging from D to Z. Because of their darker colour, champagne diamonds are graded from K to Z. Grades K to M are faint brown, N to R are light brown, and S to Z are darker brown. To learn about the factors that go into determining their value, check out our recent article on what is a champagne diamond.

Champagne Diamonds Argyle Grading Scale

Another diamond grading scale used for champagne diamonds is the Argyle grading system. The scale begins at C1 (brown) and goes to C7 (deep cognac brown). C1 to C2 are light brown, C3 to C4 are medium brown, C5 to C6 are dark brown, and C7 is referred to as a “cognac” diamond.

The Value of Champagne Diamonds

When it comes to chocolate and champagne diamond rings, the darker the colour, the higher the price. However, a champagne diamond is still often cheaper than other coloured diamonds such as pink, blue, and yellow diamonds. If you’re interested in comparing stones, learning how much pink diamonds cost will help give you a frame of reference.

There’s a wide range of colours among champagne diamonds that pair well with many styles.

How are Champagne Diamonds Formed?

While colourless diamonds and champagne diamonds are both made of carbon, the dark hue of champagne diamonds is the result of nitrogen impurities. The more impurities present, the darker the colour. 

Why Coloured Diamonds Have Become Popular

Coloured diamonds have continued to grow in popularity over the years for a number of reasons:

Balance of Colour and Hardness

In addition to being aesthetically appealing, coloured diamonds are some of the hardest precious stones on earth, making them durable. Other precious stones like sapphires and rubies are not always as long-lasting. 

Easy to Pair With Other Colours

Colourless diamonds are appealing because of their clarity, but champagne diamonds have a rich ambiance. When paired with other colours, this darkness can be even more accentuated.


The wide range of brown hues across champagne diamonds allows purchases to find a truly unique stone.


Champagne diamonds are cheaper than their colourless counterparts and create an opportunity for diamond designers to craft affordable masterpieces from stunning materials.


Champagne diamonds come in a range of grades. Given the wide variety of coloured diamonds, there’s no doubt you’ll be able to find the perfect fit to suit your unique taste.
