About this 1.28ct lab-grown cushion diamond

This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG787635783 or 787635783. Listed at 4 retailers as of November 5, 2026, with prices from $1,402 to $1,957, a $555 spread on the same certified stone. Kay Jewelers lists it at $1,957. 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.
