About this 0.39ct lab-grown marquise diamond

This 0.39ct 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 LG831651006 or 831651006. Listed at 13 retailers as of November 1, 2026, with prices from $233 to $1,280, a $1,047 spread on the same certified stone. MOH London lists it at $1,280. 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.
