About this 2.5ct lab-grown heart diamond

This 2.5ct lab-grown heart sits in the two to three carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831603947 or 831603947. Listed at 21 retailers as of October 31, 2026, with prices from €1,426 to €6,606, a €5,180 spread on the same certified stone. Brilliant Earth lists it at €6,606. 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.
