About this 0.55ct lab-grown round diamond

This 0.55ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG804672100 or 804672100. Listed at 16 retailers as of November 2, 2026, with prices from £98 to £1,000, a £902 spread on the same certified stone. MOH London lists it at £1,000. 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.
