About this 0.54ct lab-grown marquise diamond

This 0.54ct lab-grown marquise 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 LG729553062 or 729553062. Listed at 18 retailers as of October 30, 2026, with prices from £140 to £910, a £770 spread on the same certified stone. Flawless Fine Jewelry lists it at £910. 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.
