Understanding the colour of a diamond is crucial when making a purchase decision. The color grading of a diamond follows the comprehensive GIA colour scale, ranging from 'D' to 'Z'. In this scale, 'D' signifies the highest grade, denoting a diamond that is absolutely colorless. Diamonds in the white/colourless range are generally considered the most coveted, making them the most expensive.

Conversely, at the other end of the spectrum, we find the 'Z' grade, which designates diamonds that exhibit a noticeable yellowish tint. As you navigate through the colour grades, you gain valuable insights into the subtle variations in a diamond's hue.

To provide a clearer understanding, let's explore the colour grades:

  • D-F (Colorless): Diamonds in this range are virtually colourless and are of the highest quality. They exude a brilliance and sparkle that are highly sought after.

  • G-J (Near Colorless): Diamonds in this range have minimal traces of colour that are challenging to detect to the naked eye. They offer an excellent balance of quality and value.

  • K-M (Faint): Diamonds in this range may have a faint hint of colour, particularly noticeable when compared to higher grades. However, they still present good value for those seeking a more budget-friendly option.

  • N-R (Very Light): Diamonds in this range begin to show a more noticeable hint of colour. While budget-friendly, the colour becomes perceptible, especially in larger diamonds.

  • S-Z (Light): Diamonds in this range exhibit a visible tint of colour, with the 'Z' grade representing the most pronounced yellow colouration. Diamonds in this range are more budget-conscious but may not possess the pristine colorlessness of higher grades.

Understanding the intricacies of diamond colour allows you to make an informed decision based on your preferences and budget. Whether you prioritize the brilliance of a colourless diamond or opt for a more budget-friendly option with a faint hint of colour, the GIA colour scale provides a valuable guide in selecting the perfect diamond for your needs.
