About this 0.43ct lab-grown marquise diamond

This 0.43ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG679514511 or 679514511. Listed at 22 retailers as of October 30, 2026, with prices from $288 to $1,577, a $1,289 spread on the same certified stone. MOH London lists it at $1,577. 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.
