About this 0.43ct lab-grown marquise diamond

This 0.43ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG798612310 or 798612310. Listed at 21 retailers as of October 29, 2026, with prices from $278 to $1,618, a $1,340 spread on the same certified stone. MOH London lists it at $1,618. 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.
