About this 0.79ct lab-grown round diamond

This 0.79ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG830618731 or 830618731. Listed at 17 retailers as of November 1, 2026, with prices from £154 to £1,036, a £881 spread on the same certified stone. Helzberg Diamonds lists it at £1,036. 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.
