About this 1.59ct lab-grown heart diamond

This 1.59ct 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 LG825666207 or 825666207. Listed at 20 retailers as of October 31, 2026, with prices from €655 to €3,312, a €2,657 spread on the same certified stone. Brilliant Earth lists it at €3,312. 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.
