About this 0.34ct lab-grown radiant diamond

This 0.34ct lab-grown radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG655448495 or 655448495. Listed at 20 retailers as of October 29, 2026, with prices from £115 to £741, a £626 spread on the same certified stone. MOH London lists it at £741. 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.
