This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG739583468 or 739583468. Listed at 7 retailers as of November 4, 2026, with prices from $478 to $1,288, a $810 spread on the same certified stone. MOH London lists it at $1,288. 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.
