About this 3.17ct lab-grown cushion diamond

This 3.17ct 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 LG801645477 or 801645477. Listed at 3 retailers as of October 30, 2026, with prices from £2,963 to £5,008, a £2,045 spread on the same certified stone. Kay Jewelers lists it at £5,008. 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.
