About this 1.38ct lab-grown cushion diamond

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 LG840634364 or 840634364. Listed at 17 retailers as of October 30, 2026, with prices from €462 to €2,333, a €1,871 spread on the same certified stone. Helzberg Diamonds lists it at €2,333. 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.
