This 1.22ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831680105 or 831680105. Listed at 8 retailers as of October 29, 2026, with prices from $291 to $1,381, a $1,089 spread on the same certified stone. Brilliant Earth lists it at $1,381. 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.
