Diamond & Moissanite Colour

What does Colour mean?

Colour is referred to as the second most important C with Cut being the most important.

Diamond and moissanite colours range from D -Z. D means the stone is colourless and is the rarest and highest grade possible. Z means the diamond shows a visible yellowish tone. The colour of the stone is a personal preference and may also depend on your choice of shape.

Why Does Colour Matter?

It is relevant to know the colour grade of your diamond or moissanite as it can greatly impact the overall appearance of your stone. Depending on your chosen size and shape, the colour grade you select may be more obvious and evident.

For brilliant round cut diamonds, due to its design, the light reflects in a way that can hide colour more prevalently. However, for longer shapes like oval cut diamonds, you may want to select a colour grade higher as the yellow hues will be more obvious.

Again, the colour grade of your diamond or moissanite is not as important as the cut of your diamond and your choice between a D or a Z graded diamond is completely a personal choice.

At S-kin Studio our diamonds have a colour rating between a G- I and our Moissanite stones have a D colour rating. This difference is due to the higher pressure and heat requirements needed to made diamonds making it more difficult to produce D- F coloured stones. However, the colour different between D-J is barely visible to the naked eye and is the colour range most commonly used in fine jewelry.

The Different Types of Colours

Diamond and moissanite colour grading ranges from D -Z.

D grade means the diamond or moissanite is as colourless as possible. This is important as it allows for the greatest amount of light through the stone and therefore gives it the most brilliant white appearance.

Z grade means the stone will contain a very eye obvious yellowish tone throughout the stone. This may prevent the optimal amount of light through the stone minimising its shine.

D-J rated stones are most commonly used for engagement rings. D- F is categorized as colourless and G -J are considered near colourless. The difference between D-J is difficult to determine without a side by side comparison or diamond colour chart.

This colour system does not account for rare naturally coloured diamonds such as pink or red. These unique diamonds have there own colour grade system.
