About this 0.75ct lab-grown round diamond

This 0.75ct 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 LG839640556 or 839640556. Listed at 9 retailers as of November 1, 2026, with prices from £186 to £620, a £434 spread on the same certified stone. MOH London lists it at £620. 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.
