About this 1ct lab-grown heart diamond

This 1ct 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 LG818671731 or 818671731. Listed at 19 retailers as of November 1, 2026, with prices from $482 to $2,141, a $1,659 spread on the same certified stone. MOH London lists it at $2,141. 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.
