About this 0.53ct lab-grown round diamond

This 0.53ct lab-grown round 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 LG818669545 or 818669545. Listed at 19 retailers as of October 29, 2026, with prices from £110 to £1,027, a £918 spread on the same certified stone. MOH London lists it at £1,027. 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.
