How Important is the Colour of your Diamond? The Answer: Very.

Looking to switch up your jewellery collection with a coloured diamond? Or are you just looking to discover how the colour of your diamond determines the quality? Either way - you’ve come to the right place. The ‘Colour’ of a diamond is one of the infamous ‘4Cs’ of quality, the others being carat, clarity and cut. As such, it can greatly impact the price of your diamond. But, there’s an important distinction to make. ‘Coloured’ diamonds are in fact a vastly different kettle of fish than the ‘Colourless’ or ‘White’ Diamond - with the ‘White’ diamond having a colour graded scale of its own. Colourless Diamonds have their own alphabetical grading scale - as a completely colourless diamond is an exceedingly rare occurrence. As such, diamonds will often have a slight yellow tint, and you won't necessarily notice it - especially with an untrained eye. With this in mind, a colourless diamond is generally the most expensive, with a yellow tint reducing the quality & cost significantly as you move down the scale.

The ‘White’ Diamond Scale

Diamond colour is measured with the GIA (Gemological Institute of America) scale, which goes from D (completely colourless) to Z (light yellow or brown in colour). However, when you reach grade H, the slight yellow tint will be mostly undetectable, except when placed next to a diamond of a higher grade. Even still, however, this makes H colour diamonds fantastic value; as only an expert would generally be able to tell the difference between a G & H diamond (both are at a ‘near colourless’ rating), yet they are but a fraction of the cost of a D-graded diamond.

The ‘Coloured’ Diamond Scale

Diamonds that are outside the ‘normal’ coloured range, such as blues, reds and greens are significantly more rare than the yellow or brown tinges. And with diamonds, rarity means value, a lot of value. Saturated pinks, blues and greens are among the most sort after colours, and indeed the rarest, for even a slight change in colour can contribute to a significant loss in value. The GIA scale for grading such diamonds is highly complex, however, and requires a specialist in a lab to truly understand the rarity and value. With these fancy colours, the colour itself is the dominating factor when it comes to price. If the diamond presents an attractive, visible face-up colour, it will often cost more when compared to a diamond with less inclusions but a dimmer, less saturated colour.
