About this 0.52ct lab-grown radiant diamond

This 0.52ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818659067 or 818659067. Listed at 18 retailers as of November 1, 2026, with prices from £161 to £874, a £713 spread on the same certified stone. Reve Diamonds lists it at £874. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
