About this 1.23ct lab-grown cushion diamond

This 1.23ct 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 LG633442273 or 633442273. Listed at 4 retailers as of November 5, 2026, with prices from $1,340 to $1,886, a $546 spread on the same certified stone. Kay Jewelers lists it at $1,886. 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.
