About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840635024 or 840635024. Listed at 15 retailers as of November 1, 2026, with prices from $524 to $2,485, a $1,961 spread on the same certified stone. Helzberg Diamonds lists it at $2,485. 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.
