About this 1.31ct lab-grown cushion diamond

This 1.31ct 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 very-good cut grade and certified by IGI LG839684864 or 839684864. Listed at 19 retailers as of October 29, 2026, with prices from €324 to €2,444, a €2,120 spread on the same certified stone. Do Amore Diamonds lists it at €2,444. 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.
