This 1.58ct 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 LG782690947 or 782690947. Listed at 11 retailers as of November 2, 2026, with prices from €648 to €2,523, a €1,875 spread on the same certified stone. Brilliant Earth lists it at €2,523. 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.
