About this 5.03ct lab-grown cushion diamond

This 5.03ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG732563881 or 732563881. Listed at 13 retailers as of October 29, 2026, with prices from £2,402 to £8,670, a £6,268 spread on the same certified stone. Taylor and Hart lists it at £8,670. 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.
