About this 0.52ct lab-grown round diamond

This 0.52ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816603139 or 816603139. Listed at 18 retailers as of October 29, 2026, with prices from $225 to $2,348, a $2,123 spread on the same certified stone. MOH London lists it at $2,348. 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.
