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 LG825632720 or 825632720. Listed at 14 retailers as of November 1, 2026, with prices from $478 to $2,826, a $2,348 spread on the same certified stone. Brilliant Earth lists it at $2,826. 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.
