About this 0.57ct lab-grown oval diamond

This 0.57ct lab-grown oval 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 LG812620311 or 812620311. Listed at 22 retailers as of October 30, 2026, with prices from $348 to $1,976, a $1,629 spread on the same certified stone. Reve Diamonds lists it at $1,976. 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.
