This 1.52ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830669830 or 830669830. Listed at 20 retailers as of November 4, 2026, with prices from €484 to €3,923, a €3,439 spread on the same certified stone. Brilliant Earth lists it at €3,923. 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.
