This 1.22ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG816608163 or 816608163. Listed at 13 retailers as of October 28, 2026, with prices from $341 to $2,045, a $1,704 spread on the same certified stone. Queensmith lists it at $2,045. 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.
