About this 0.56ct lab-grown marquise diamond

This 0.56ct 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 LG799653919 or 799653919. Listed at 9 retailers as of October 29, 2026, with prices from $340 to $912, a $572 spread on the same certified stone. MOH London lists it at $912. 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.
