About this 0.51ct lab-grown marquise diamond
This 0.51ct lab-grown marquise 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 LG813643721 or 813643721. Listed at 17 retailers as of October 26, 2026, with prices from €174 to €1,009, a €836 spread on the same certified stone. MOH London lists it at €1,009. 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.
