About this 0.51ct lab-grown marquise diamond

This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818662694 or 818662694. Listed at 19 retailers as of November 3, 2026, with prices from $559 to $2,582, a $2,023 spread on the same certified stone. Reve Diamonds lists it at $2,582. 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.
