About this 3.53ct lab-grown cushion diamond

This 3.53ct 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 LG734516209 or 734516209. Listed at 16 retailers as of October 30, 2026, with prices from £1,982 to £7,171, a £5,188 spread on the same certified stone. Taylor and Hart lists it at £7,171. 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.
