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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816637310 or 816637310. Listed at 14 retailers as of October 30, 2026, with prices from €269 to €1,504, a €1,234 spread on the same certified stone. Do Amore Diamonds lists it at €1,504. 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.
