About this 0.65ct lab-grown marquise diamond

This 0.65ct 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 LG821659891 or 821659891. Listed at 19 retailers as of November 2, 2026, with prices from $378 to $2,144, a $1,766 spread on the same certified stone. Riddles Jewelry lists it at $2,144. 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.
