About this 0.73ct lab-grown heart diamond

This 0.73ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620861 or 840620861. Listed at 14 retailers as of October 27, 2026, with prices from €196 to €1,123, a €927 spread on the same certified stone. Reve Diamonds lists it at €1,123. 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.
