About this 0.55ct lab-grown oval diamond

This 0.55ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818634663 or 818634663. Listed at 4 retailers as of October 26, 2026, with prices from £239 to £679, a £440 spread on the same certified stone. MOH London lists it at £679. 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.
