About this 0.5ct lab-grown marquise diamond

This 0.5ct 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 LG628474093 or 628474093. Listed at 2 retailers as of November 2, 2026, with prices from $132 to $780, a $648 spread on the same certified stone. Brilliant Earth lists it at $780. 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.
