About this 0.52ct lab-grown marquise diamond

This 0.52ct 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 LG816662574 or 816662574. Listed at 17 retailers as of October 30, 2026, with prices from $236 to $1,308, a $1,072 spread on the same certified stone. Reve Diamonds lists it at $1,308. 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.
