About this 0.52ct lab-grown marquise diamond

This 0.52ct 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 LG726556433 or 726556433. Listed at 10 retailers as of October 29, 2026, with prices from £190 to £658, a £467 spread on the same certified stone. MOH London lists it at £658. 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.
