A 3-carat F colour diamond is a sophisticated option for engagement rings or luxury jewellery, providing near-colourless beauty with excellent brilliance. Its refined appearance offers a balance of purity and value, delivering a timeless look with modern elegance and enduring charm.
Lab-grown diamonds are genuine diamonds, developed in controlled labs using advanced techniques that replicate natural diamond formation. They are optically, chemically, and physically identical to mined diamonds—only the origin differs.
Lab-grown options are typically 30% to 50% less expensive, allowing you to invest in a larger or higher-grade stone without compromising ethics or aesthetics.
At RÊVE Diamonds, all our lab-created diamonds are independently certified—most commonly by IGI or GIA, two of the industry’s most respected gemological labs.
Call us on 020 3585 2295 or chat with our diamond experts to find your perfect 3 carat F colour lab-grown diamond today.
Prices range from £2,500 to £20,000 depending on cut, colour, clarity, and overall quality.
