About this 1.3ct lab-grown cushion diamond

This 1.3ct 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 LG823695112 or 823695112. Listed at 15 retailers as of November 4, 2026, with prices from €518 to €2,530, a €2,013 spread on the same certified stone. Brilliant Earth lists it at €2,530. 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.
