About this 8.25ct lab-grown cushion diamond

This 8.25ct lab-grown cushion sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG597360741 or 597360741. Listed at 12 retailers as of October 31, 2026, with prices from £1,183 to £4,456, a £3,273 spread on the same certified stone. Brilliant Earth lists it at £4,456. 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.
