About this 0.79ct lab-grown round diamond

This 0.79ct 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 LG831697474 or 831697474. Listed at 19 retailers as of October 29, 2026, with prices from £142 to £995, a £853 spread on the same certified stone. Helzberg Diamonds lists it at £995. 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.
