About this 1.04ct lab-grown heart diamond

This 1.04ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818662856 or 818662856. Listed at 17 retailers as of October 29, 2026, with prices from $546 to $2,375, a $1,829 spread on the same certified stone. MOH London lists it at $2,375. 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.
