This 1.91ct 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 standard cut grade and certified by IGI LG836603142 or 836603142. Listed at 10 retailers as of October 31, 2026, with prices from €783 to €3,455, a €2,672 spread on the same certified stone. Brilliant Earth lists it at €3,455. 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.
