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 LG738515335 or 738515335. Listed at 27 retailers as of October 31, 2026, with prices from $305 to $3,708, a $3,403 spread on the same certified stone. Do Amore Diamonds lists it at $3,708. 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.
