About this 3.52ct lab-grown cushion diamond

This 3.52ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG733553040 or 733553040. Listed at 17 retailers as of October 29, 2026, with prices from £1,977 to £7,151, a £5,174 spread on the same certified stone. Taylor and Hart lists it at £7,151. 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.
