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 LG845670889 or 845670889. Listed at 16 retailers as of October 31, 2026, with prices from £976 to £7,456, a £6,480 spread on the same certified stone. Brilliant Earth lists it at £7,456. 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.
