About this 1.24ct lab-grown heart diamond

This 1.24ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844659507 or 844659507. Listed at 15 retailers as of November 6, 2026, with prices from €313 to €1,917, a €1,603 spread on the same certified stone. Brilliant Earth lists it at €1,917. 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.
