This 1.38ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840629940 or 840629940. Listed at 16 retailers as of November 4, 2026, with prices from €438 to €2,322, a €1,883 spread on the same certified stone. Helzberg Diamonds lists it at €2,322. 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.
