Looking for a fancy coloured loose diamond or fancy coloured diamond jewellery? please contact us to arrange a visit to our showroom or search through our fancy coloured diamonds inventory online.
In short: Fancy coloured diamonds are best sourced from GIA-certified specialists with disclosed colour-treatment status — natural fancy colours command 5-100x the price of treated equivalents at identical 4Cs. Top UK channels: Hatton Garden bespoke jewellers (custom commissions, 2-2.5 weeks lead time), Bond Street heritage houses (Tiffany, Cartier, Graff), and reputable online specialists. Always verify the GIA Colored Diamond Origin Report distinguishes natural from treated.

Buying fancy coloured diamonds: frequently asked questions
Where should I buy a fancy coloured diamond?
From a specialist who provides an independent coloured-diamond report and clear photos or video. Colour is subjective, so you want to see the exact stone.
What should the certificate say?
It should give the colour grade — hue, tone and saturation — and clearly state whether the colour is natural or treated.
Should I buy natural or lab-grown?
It depends on your budget and priorities. Natural stones are rarer and hold rarity value; lab-grown gives you the same colour for far less.
Can I see coloured diamonds in person?
Yes. Booking a showroom appointment lets you compare colours in daylight, which photos can't fully capture. Rêve shows coloured diamonds in London, New York and Los Angeles.
