About this 0.68ct lab-grown marquise diamond

This 0.68ct 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 LG660435735 or 660435735. Listed at 22 retailers as of October 30, 2026, with prices from $260 to $3,367, a $3,107 spread on the same certified stone. Do Amore Diamonds lists it at $3,367. 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.
