This 3.21ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG729540963 or 729540963. Listed at 4 retailers as of October 28, 2026, with prices from £3,560 to £5,054, a £1,494 spread on the same certified stone. Kay Jewelers lists it at £5,054. 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.
