About this 1.22ct lab-grown cushion diamond

This 1.22ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605312242 or 605312242. Listed at 4 retailers as of November 2, 2026, with prices from €595 to €838, a €243 spread on the same certified stone. Kay Jewelers lists it at €838. 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.
