About this 0.74ct lab-grown marquise diamond

This 0.74ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG815641240 or 815641240. Listed at 16 retailers as of November 4, 2026, with prices from $787 to $3,560, a $2,773 spread on the same certified stone. Riddles Jewelry lists it at $3,560. 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.
