About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799677139 or 799677139. Listed at 20 retailers as of November 1, 2026, with prices from $575 to $2,784, a $2,209 spread on the same certified stone. MOH London lists it at $2,784. 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.
