About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG700511677 or 700511677. Listed at 22 retailers as of October 25, 2026, with prices from $426 to $2,314, a $1,889 spread on the same certified stone. Queensmith lists it at $2,314. 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.
