Are you looking to buy a lab-grown loose diamond or engagement ring? Select from the thousands of certified diamonds in our collection. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — available at 50–70% less than the cost of a naturally mined stone.
A 3-carat D colour Internally Flawless diamond is an exquisite choice for engagement rings or bespoke jewellery. Completely colourless and free from inclusions, it delivers unmatched brilliance and clarity—perfect for those who value ultimate purity and timeless beauty.
Lab-grown diamonds are real diamonds created in a laboratory setting, using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) process. They are physically, chemically, and visually the same as mined diamonds—so much so that even expert gemologists require advanced equipment to tell them apart.
Choosing lab-grown means saving 30% to 50% over the price of a natural diamond, all while making an environmentally conscious and ethical decision.
All REVE Diamonds’ lab-grown stones are independently certified, most commonly by IGI or GIA.

D is the highest color grade, meaning the diamond is completely colorless. IF (Internally Flawless) means there are no internal imperfections under 10x magnification—together, they represent diamond perfection.
Prices typically range from £4,000 to £22,000, depending on the diamond’s cut, colour, polish, symmetry, and certification. The D colour and IF clarity grades command a premium.
Lab grown diamonds are chemically and optically identical to mined diamonds. A 3ct D IF lab grown diamond offers the same beauty and quality at a significantly lower price and with a lower environmental impact.
Yes. A D IF diamond is completely colourless and internally flawless, offering superior visual purity and brilliance when compared to near-colourless or slightly included stones.
A 3 carat diamond typically measures around 9.3 mm in diameter for a round cut or 9.5 mm x 9.5 mm for a square cut like Asscher. Clarity and colour do not affect the physical size of the diamond.
