About this 0.78ct lab-grown marquise diamond

This 0.78ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815641272 or 815641272. Listed at 22 retailers as of November 4, 2026, with prices from $585 to $3,357, a $2,772 spread on the same certified stone. Riddles Jewelry lists it at $3,357. 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.
