This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840619698 or 840619698. Listed at 7 retailers as of November 5, 2026, with prices from $444 to $1,967, a $1,522 spread on the same certified stone. MOH London lists it at $1,967. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
