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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG803665279 or 803665279. Listed at 14 retailers as of November 3, 2026, with prices from $459 to $2,643, a $2,183 spread on the same certified stone. MOH London lists it at $2,643. 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.
