About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion 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 LG836621509 or 836621509. Listed at 16 retailers as of October 31, 2026, with prices from €263 to €1,400, a €1,137 spread on the same certified stone. Brilliant Earth lists it at €1,400. 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.
