About this 0.77ct lab-grown round diamond

This 0.77ct 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 LG839640550 or 839640550. Listed at 9 retailers as of November 4, 2026, with prices from $328 to $1,231, a $903 spread on the same certified stone. MOH London lists it at $1,231. 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.
