This 1.31ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG805697811 or 805697811. Listed at 4 retailers as of October 31, 2026, with prices from €1,028 to €1,423, a €395 spread on the same certified stone. Kay Jewelers lists it at €1,423. 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.
