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 VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG840640100 or 840640100. Listed at 17 retailers as of October 25, 2026, with prices from $239 to $1,370, a $1,131 spread on the same certified stone. Brilliant Earth lists it at $1,370. 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.
