This 1.71ct 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 LG825665153 or 825665153. Listed at 6 retailers as of October 31, 2026, with prices from €1,120 to €5,254, a €4,134 spread on the same certified stone. Do Amore Diamonds lists it at €5,254. 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.
