This 1.03ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840611849 or 840611849. Listed at 11 retailers as of October 26, 2026, with prices from €160 to €1,183, a €1,023 spread on the same certified stone. MOH London lists it at €1,183. 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.
