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 LG639406854 or 639406854. Listed at 7 retailers as of November 1, 2026, with prices from $507 to $1,749, a $1,242 spread on the same certified stone. MOH London lists it at $1,749. 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.
