Colourful lab-grown diamonds are redefining what it means to be rare in the diamond industry. Shades that were once limited to extremely rare natural diamonds are now accessible, without compromising authenticity, brilliance, or quality.

Rather than relying on chance, lab-grown diamonds allow colour to become a deliberate choice, offering couples more freedom when designing an engagement ring that feels personal and meaningful.

Colourful lab-grown diamonds (also called "fancy diamonds") are real diamonds created in a controlled laboratory environment.

Chemically, physically, and optically, they are identical to natural diamonds. The only difference is their origin,

• In natural diamonds, colour occurs under rare geological conditions over millions of years.
• In lab-grown diamonds, colour develops through carefully controlled growth processes, that allow precise and consistent results.

Available colour options for engagement rings include:

• Yellow

• Pink

• Blue

• Green

• Grey

• Champagne and cognac tones

Each diamond is graded for colour intensity, cut, clarity, and carat weight, just like natural fancy-colored diamonds.

Fancy natural diamonds are among the rarest gemstones in the world. Their limited availability meant they were often reserved for collectors, museums, or exceptional bespoke pieces.

But Lab-grown diamonds remove this limitation. They make distinctive colours accessible for engagement rings while preserving the authenticity of a real diamond. Rarity becomes a matter of choice, not chance.

Not really. Lab-grown diamonds typically cost 60–85% less than comparable natural diamonds of the same size and quality.

But prices vary depending on colour, colour intensity, carat weight, clarity, and cut.
