About this 0.78ct lab-grown round diamond

This 0.78ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG789606199 or 789606199. Listed at 10 retailers as of October 28, 2026, with prices from £207 to £715, a £509 spread on the same certified stone. MOH London lists it at £715. 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.
