About this 0.57ct lab-grown round diamond

This 0.57ct lab-grown round 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 LG840623504 or 840623504. Listed at 8 retailers as of October 28, 2026, with prices from $179 to $1,665, a $1,486 spread on the same certified stone. MOH London lists it at $1,665. 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.
