About this 5.06ct lab-grown cushion diamond

This 5.06ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG739588297 or 739588297. Listed at 17 retailers as of October 29, 2026, with prices from £2,754 to £9,996, a £7,242 spread on the same certified stone. Taylor and Hart lists it at £9,996. 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.
