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 LG818657644 or 818657644. Listed at 11 retailers as of November 4, 2026. 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.
