About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825655820 or 825655820. Listed at 16 retailers as of November 6, 2026, with prices from £426 to £4,968, a £4,542 spread on the same certified stone. Brilliant Earth lists it at £4,968. 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.
