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 LG831604135 or 831604135. Listed at 18 retailers as of October 30, 2026, with prices from $332 to $1,835, a $1,502 spread on the same certified stone. Reve Diamonds lists it at $1,835. 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.
