About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round sits in the sub-half-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG791649781 or 791649781. Listed at 8 retailers as of November 1, 2026, with prices from $234 to $1,323, a $1,089 spread on the same certified stone. MOH London lists it at $1,323. 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.
