About this 1.48ct lab-grown cushion diamond

This 1.48ct 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 very-good cut grade and certified by IGI LG836619518 or 836619518. Listed at 15 retailers as of October 29, 2026, with prices from £388 to £2,493, a £2,105 spread on the same certified stone. Brilliant Earth lists it at £2,493. 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.
