This 3.5ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG717586082 or 717586082. Listed at 16 retailers as of October 31, 2026, with prices from £796 to £3,068, a £2,272 spread on the same certified stone. Novita Diamonds lists it at £3,068. 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.
