About this 0.81ct lab-grown round diamond

This 0.81ct lab-grown round sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG839640608 or 839640608. Listed at 8 retailers as of November 1, 2026, with prices from $330 to $1,114, a $784 spread on the same certified stone. MOH London lists it at $1,114. 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.
