About this 0.55ct lab-grown oval diamond

This 0.55ct lab-grown oval 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 LG806628719 or 806628719. Listed at 18 retailers as of October 26, 2026, with prices from £136 to £790, a £655 spread on the same certified stone. MOH London lists it at £790. 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.
