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 $207 to $1,388, a $1,181 spread on the same certified stone. Helzberg Diamonds lists it at $1,388. 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.
