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 LG638415529 or 638415529. Listed at 19 retailers as of October 30, 2026, with prices from $391 to $2,173, a $1,782 spread on the same certified stone. Brilliant Earth lists it at $2,173. 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.
