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 30, 2026, with prices from €283 to €1,464, a €1,182 spread on the same certified stone. Riddles Jewelry lists it at €1,464. 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.
