About this 0.5ct lab-grown marquise diamond

This 0.5ct 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 LG788681809 or 788681809. Listed at 18 retailers as of October 30, 2026, with prices from $188 to $1,086, a $898 spread on the same certified stone. MOH London lists it at $1,086. 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.
