This 1.18ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG821651756 or 821651756. Listed at 12 retailers as of October 30, 2026, with prices from €325 to €1,466, a €1,141 spread on the same certified stone. Novita Diamonds lists it at €1,466. 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.
