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 LG818657607 or 818657607. Listed at 18 retailers as of November 1, 2026, with prices from $527 to $2,339, a $1,812 spread on the same certified stone. MOH London lists it at $2,339. 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.
