About this 0.85ct lab-grown heart diamond

This 0.85ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818671771 or 818671771. Listed at 16 retailers as of October 29, 2026, with prices from $402 to $1,749, a $1,347 spread on the same certified stone. MOH London lists it at $1,749. 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.
