Why Choose a Fancy Colour Diamond?

Rare Natural Colour — Fancy colour diamonds are valued for visible body colour rather than colourlessness, making each stone feel distinctive and personal.

Diamond Durability — They offer the hardness and everyday wearability of diamond, making them suitable for engagement rings and other fine jewellery when set appropriately.

Expressive Design Potential — Colour can shape the entire mood of a piece, from soft champagne and cognac tones to vivid pink, yellow, blue or green diamonds.

Highly Individual Character — Fancy colour diamonds often have nuances of tone, saturation and secondary hue, so choosing one is usually more personal than selecting by numbers alone.

Fancy Colour Diamond FAQs

Q: What is a fancy colour diamond?

A: A fancy colour diamond is a natural diamond with a noticeable body colour beyond the usual white-to-tinted diamond grading scale. These colours may include yellow, pink, champagne, cognac, brown, grey, blue, green, orange and other rarer hues. The colour may be subtle or intense, depending on the stone.

Q: How are fancy colour diamonds graded?

A: Fancy colour diamonds are usually assessed by hue, tone and saturation rather than the standard D to Z white diamond colour scale. Terms such as Fancy Light, Fancy, Fancy Intense and Fancy Vivid describe the strength of colour, but the stone still needs to be judged in person for beauty, cut, brightness and suitability.

Q: Are fancy colour diamonds natural?

A: Some fancy colour diamonds are naturally coloured, while others may be treated or enhanced. Disclosure is important. We distinguish between natural fancy colour, treated colour and lab-grown colour where that information is known, and we will explain what it means for value and suitability.

Q: Are fancy colour diamonds suitable for engagement rings?

A: Yes. Fancy colour diamonds are still diamonds, so they are very durable and can be excellent for engagement rings. The best setting depends on the stone colour, cut, size and shape. Some colours are enhanced by yellow or rose gold, while others benefit from contrast with white metal.
