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 LG823694927 or 823694927. Listed at 19 retailers as of October 29, 2026, with prices from $389 to $1,895, a $1,506 spread on the same certified stone. MOH London lists it at $1,895. 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.
