About this 1.79ct lab-grown cushion diamond

This 1.79ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818683537 or 818683537. Listed at 11 retailers as of October 30, 2026, with prices from $1,430 to $5,755, a $4,325 spread on the same certified stone. Brilliant Earth lists it at $5,755. 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.
