About this 0.67ct lab-grown marquise diamond

This 0.67ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG743538675 or 743538675. Listed at 23 retailers as of November 1, 2026, with prices from $290 to $3,388, a $3,098 spread on the same certified stone. Do Amore Diamonds lists it at $3,388. 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.
