This 1.25ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG640416402 or 640416402. Listed at 13 retailers as of November 1, 2026, with prices from €243 to €949, a €706 spread on the same certified stone. MOH London lists it at €949. 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.
