Welcome to Rêve Diamonds, your trusted GIA certified diamond dealer in London. We specialise in providing the finest wholesale diamonds, offering you unparalleled quality at unbeatable prices.
A 1 carat D color lab-grown diamond sits at the very top of the diamond color scale. This grade is a favorite for engagement rings and fine jewelry where brilliance and a bright white sparkle matter most.
Lab-grown diamonds are real diamonds created using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) method in a lab. These stones share the same physical, chemical, and visual properties as mined diamonds—only their origin differs. Even trained gemologists require special tools to tell them apart.
Choosing lab-grown means saving 30% to 50% over the cost of natural diamonds while making a sustainable and ethical choice.
All Rève Diamonds' lab-grown diamonds are independently certified, typically by IGI or GIA.

Prices typically range from $1,100 to $4,600, reflecting the premium for this color grade.
D is the highest grade on the GIA color scale, meaning the diamond is completely colorless with no detectable tint.
Color is hardest to detect in smaller stones. In a 1 carat diamond, grades down to G or H can look near-colorless to the naked eye, so D color is chosen mainly by buyers who want the highest possible grade.
