4 Carat D Colour Lab-Grown Diamond
A 4 carat D colour lab-grown diamond represents the top of the diamond colour scale. This grade is prized for engagement rings and fine jewellery where brilliance and a bright white sparkle are the priority. At 4 carats, this is a substantial, statement-size diamond.
Why Choose Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds, produced in high-tech labs that replicate natural geological conditions. They match mined diamonds in chemical composition, physical properties, and optical brilliance — the only difference is how they're formed. Lab-grown diamonds offer excellent value, often costing 30% to 50% less than mined diamonds of the same quality.
At Rêve Diamonds, we offer a wide range of lab-grown diamonds that are certified by leading gemological institutes such as IGI or GIA, ensuring authenticity and quality with every purchase.

D is the highest grade on the GIA colour scale, meaning the diamond is completely colourless with no detectable tint.
Do I need D colour in a 4 carat diamond?
D colour is most noticeable in larger stones or diamonds with wider tables, so at larger carat weights it becomes more relevant to choosing the top grade.
