About this 3.01ct lab-grown cushion diamond

This 3.01ct 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 LG742521023 or 742521023. Listed at 21 retailers as of October 31, 2026, with prices from £1,155 to £5,814, a £4,659 spread on the same certified stone. Brilliant Earth lists it at £5,814. 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.
