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 LG806628748 or 806628748. Listed at 17 retailers as of October 26, 2026, with prices from $214 to $1,069, a $855 spread on the same certified stone. MOH London lists it at $1,069. 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.
