About this 3.21ct lab-grown cushion diamond

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 standard cut grade and certified by IGI LG752505082 or 752505082. Listed at 17 retailers as of October 27, 2026, with prices from £612 to £2,756, a £2,144 spread on the same certified stone. Rare Carat lists it at £2,756. 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.
