About this 0.46ct lab-grown marquise diamond

This 0.46ct 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 LG799697351 or 799697351. Listed at 12 retailers as of November 1, 2026, with prices from $275 to $1,589, a $1,314 spread on the same certified stone. MOH London lists it at $1,589. 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.
