About this 0.57ct lab-grown marquise diamond

This 0.57ct 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 LG799697364 or 799697364. Listed at 21 retailers as of October 30, 2026, with prices from $335 to $1,746, a $1,411 spread on the same certified stone. Riddles Jewelry lists it at $1,746. 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.
