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 LG803675423 or 803675423. Listed at 22 retailers as of October 30, 2026, with prices from $337 to $1,949, a $1,612 spread on the same certified stone. Reve Diamonds lists it at $1,949. 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.
