About this 3.34ct lab-grown cushion diamond

This 3.34ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG662408543 or 662408543. Listed at 24 retailers as of October 29, 2026, with prices from £1,392 to £8,335, a £6,943 spread on the same certified stone. Brilliant Earth lists it at £8,335. 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.
