About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG801643235 or 801643235. Listed at 4 retailers as of October 31, 2026, with prices from €659 to €927, a €268 spread on the same certified stone. Kay Jewelers lists it at €927. 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.
