This 1.54ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG851609353 or 851609353. Listed at 16 retailers as of October 30, 2026, with prices from €330 to €2,524, a €2,194 spread on the same certified stone. Brilliant Earth lists it at €2,524. 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.
