This 1.5ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825632585 or 825632585. Listed at 20 retailers as of October 30, 2026, with prices from €579 to €3,187, a €2,607 spread on the same certified stone. Brilliant Earth lists it at €3,187. 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.
