About this 0.77ct lab-grown heart diamond

This 0.77ct lab-grown heart 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 LG818671770 or 818671770. Listed at 17 retailers as of November 1, 2026, with prices from $490 to $2,182, a $1,692 spread on the same certified stone. MOH London lists it at $2,182. 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.
