About this 1.23ct lab-grown heart diamond

This 1.23ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836696222 or 836696222. Listed at 14 retailers as of October 31, 2026, with prices from €368 to €1,522, a €1,154 spread on the same certified stone. Brilliant Earth lists it at €1,522. 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.
