About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830621820 or 830621820. Listed at 19 retailers as of November 3, 2026, with prices from €366 to €2,361, a €1,995 spread on the same certified stone. Brilliant Earth lists it at €2,361. 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.
