This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG737565888 or 737565888. Listed at 18 retailers as of November 1, 2026, with prices from €352 to €2,256, a €1,904 spread on the same certified stone. Brilliant Earth lists it at €2,256. 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.
