About this 4.03ct lab-grown cushion diamond

This 4.03ct 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 LG712569516 or 712569516. Listed at 19 retailers as of October 31, 2026, with prices from £2,205 to £7,272, a £5,067 spread on the same certified stone. Taylor and Hart lists it at £7,272. 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.
