This 0.84ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616809 or 778616809. Listed at 10 retailers as of November 1, 2026, with prices from $623 to $3,909, a $3,287 spread on the same certified stone. MOH London lists it at $3,909. 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.
