About this 0.99ct lab-grown asscher diamond

This 0.99ct lab-grown asscher sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840635096 or 840635096. Listed at 18 retailers as of October 29, 2026, with prices from £300 to £1,460, a £1,160 spread on the same certified stone. MOH London lists it at £1,460. 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.
