About this 5.07ct lab-grown cushion diamond

This 5.07ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830677405 or 830677405. Listed at 9 retailers as of October 30, 2026, with prices from £1,318 to £4,154, a £2,836 spread on the same certified stone. With Clarity lists it at £4,154. 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.
