Subtle differences in colour can dramatically affect a diamond's value.  Two diamonds of the same clarity, weight, and cut can differ in value based on colour alone. Even the slightest hint of colour can make a dramatic difference in value.

Diamonds come in many colours.  Diamonds that range from colourless to light yellow and brown fall within the normal colour range.  Within that range, colourless diamonds are the most rare, so they are the most valuable.  They set the standard for grading and pricing other diamonds in the normal colour range.

The GIA D-to-Z scale is the industry standard for colour-grading diamonds.  Each letter represents a range of colour based on a diamond's tone and saturation.


At Minar Jewellers we only sell diamonds with a colour grade of J and higher.
