Lab-Grown Colour Diamonds
Lab-grown fancy colour diamonds are created in a controlled environment. They have the same essential properties as natural diamonds, but their origin is different. Their colour may develop during growth or result from treatment, so a grading report can help clarify the details
Natural Colour Diamonds
Formed deep within the Earth, natural fancy colour diamonds get their colour from variations in their structure or trace elements. Their natural origin and rarity make each stone distinctive. A grading report can help confirm whether the colour is natural or treated.

Fancy Colour Diamond FAQ
What is a fancy colour diamond?
A fancy colour diamond displays a noticeable colour beyond the usual colourless-to-light range. Its appearance is described by its hue and the strength and character of that colour. Each diamond is unique, so compare the individual stone and its grading information.
Are fancy colour diamonds natural or lab-grown?
They can be either. Natural fancy colour diamonds formed in the earth; lab-grown fancy colour diamonds were created in a controlled environment. Product listings identify the origin of each diamond.
Are all coloured diamonds naturally coloured?
No. Some diamonds have colour that is natural, while others have been treated to change or enhance their colour. Review the grading report and product details for information about the individual diamond’s colour origin and any disclosed treatments.
Do fancy colour diamonds come with a grading report?
Many of the larger fancy colour diamonds in our selection are accompanied by a grading report, but documentation varies by stone. Check the product listing for the available report and details, or contact us before purchasing if you have questions.
