About this 1.08ct lab-grown cushion diamond

This 1.08ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831679807 or 831679807. Listed at 9 retailers as of October 29, 2026, with prices from $351 to $2,280, a $1,929 spread on the same certified stone. Brilliant Earth lists it at $2,280. 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.
