Coloured diamonds, also known as fancy coloured diamonds, are diamonds with natural or lab-grown hues such as pink, yellow, blue, green, or champagne. These vibrant colours result from unique structural properties or trace elements within the diamond.

Natural coloured diamonds get their hues from unique conditions during their formation. For example, yellow diamonds are caused by nitrogen, while blue diamonds owe their colour to boron. Lab-grown coloured diamonds achieve their colours through controlled processes that replicate natural conditions.

Yes, both natural and lab-grown coloured diamonds are real diamonds. They have the same chemical, physical, and optical properties as traditional white diamonds but come in a variety of stunning colours.

Absolutely! Natural coloured diamonds are exceptionally rare, with only 1 in 10,000 diamonds exhibiting a fancy colour. This rarity makes them highly sought after by collectors and jewellery enthusiasts.

Yes! Lab-grown coloured diamonds offer the same beauty and brilliance as natural diamonds at a more affordable price. They are also an ethical and environmentally friendly choice for jewellery.
