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 very-good cut grade and certified by IGI LG818658537 or 818658537. Listed at 18 retailers as of October 31, 2026, with prices from €364 to €2,300, a €1,936 spread on the same certified stone. Brilliant Earth lists it at €2,300. 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.
