About this 1.36ct lab-grown cushion diamond

This 1.36ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840635031 or 840635031. Listed at 16 retailers as of October 30, 2026, with prices from €430 to €2,193, a €1,763 spread on the same certified stone. Helzberg Diamonds lists it at €2,193. 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.
