About this 0.55ct lab-grown marquise diamond

This 0.55ct 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 LG812621454 or 812621454. Listed at 21 retailers as of November 4, 2026, with prices from $153 to $1,045, a $892 spread on the same certified stone. Reve Diamonds lists it at $1,045. 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.
