About this 0.91ct lab-grown heart diamond

This 0.91ct 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 LG639414592 or 639414592. Listed at 6 retailers as of October 30, 2026, with prices from $295 to $2,020, a $1,725 spread on the same certified stone. Brilliant Earth lists it at $2,020. 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.
