About this 0.84ct lab-grown round diamond

This 0.84ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840635085 or 840635085. Listed at 13 retailers as of October 29, 2026, with prices from £263 to £1,040, a £777 spread on the same certified stone. Helzberg Diamonds lists it at £1,040. 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.
