This 3.17ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG659416259 or 659416259. Listed at 4 retailers as of October 30, 2026, with prices from £1,887 to £2,687, a £799 spread on the same certified stone. Kay Jewelers lists it at £2,687. 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.
