About this 3.3ct lab-grown cushion diamond

This 3.3ct 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 LG735587836 or 735587836. Listed at 17 retailers as of October 29, 2026, with prices from £1,427 to £5,185, a £3,758 spread on the same certified stone. Taylor and Hart lists it at £5,185. 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.
