About this 1.04ct lab-grown cushion diamond

This 1.04ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840622336 or 840622336. Listed at 15 retailers as of October 31, 2026, with prices from £356 to £1,731, a £1,375 spread on the same certified stone. Brilliant Earth lists it at £1,731. 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.
