This 1.33ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG831696418 or 831696418. Listed at 18 retailers as of October 29, 2026, with prices from €483 to €1,924, a €1,441 spread on the same certified stone. Helzberg Diamonds lists it at €1,924. 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.
