This 1.54ct 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 LG825666390 or 825666390. Listed at 21 retailers as of October 31, 2026, with prices from €636 to €3,222, a €2,587 spread on the same certified stone. Brilliant Earth lists it at €3,222. 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.
