About this 1.42ct lab-grown cushion diamond

This 1.42ct 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 very-good cut grade and certified by IGI LG605314531 or 605314531. Listed at 4 retailers as of October 30, 2026, with prices from €726 to €1,159, a €433 spread on the same certified stone. Jared lists it at €1,159. 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.
