About this 0.57ct lab-grown marquise diamond

This 0.57ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817625563 or 817625563. Listed at 20 retailers as of October 29, 2026, with prices from $441 to $2,285, a $1,844 spread on the same certified stone. Riddles Jewelry lists it at $2,285. 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.
