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 LG819627468 or 819627468. Listed at 22 retailers as of November 1, 2026, with prices from $204 to $1,207, a $1,003 spread on the same certified stone. Reve Diamonds lists it at $1,207. 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.
