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 LG799676779 or 799676779. Listed at 20 retailers as of October 29, 2026, with prices from £125 to £812, a £688 spread on the same certified stone. Reve Diamonds lists it at £812. 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.
