About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG782651571 or 782651571. Listed at 24 retailers as of October 27, 2026, with prices from $272 to $2,143, a $1,871 spread on the same certified stone. Queensmith lists it at $2,143. 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.
