This 1.55ct 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 LG817678264 or 817678264. Listed at 14 retailers as of October 31, 2026, with prices from €417 to €2,227, a €1,810 spread on the same certified stone. Novita Diamonds lists it at €2,227. 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.
