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 LG728558163 or 728558163. Listed at 23 retailers as of October 30, 2026, with prices from $280 to $2,876, a $2,595 spread on the same certified stone. Do Amore Diamonds lists it at $2,876. 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.
