About this 1.22ct lab-grown cushion diamond

This 1.22ct 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 LG788634957 or 788634957. Listed at 13 retailers as of October 29, 2026, with prices from $598 to $2,620, a $2,022 spread on the same certified stone. MOH London lists it at $2,620. 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.
