About this 0.98ct lab-grown heart diamond

This 0.98ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG689517618 or 689517618. Listed at 9 retailers as of October 26, 2026, with prices from $816 to $2,375, a $1,560 spread on the same certified stone. MOH London lists it at $2,375. 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.
