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 LG816662354 or 816662354. Listed at 9 retailers as of October 30, 2026, with prices from $520 to $3,371, a $2,851 spread on the same certified stone. Do Amore Diamonds lists it at $3,371. 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.
