About this 8.31ct lab-grown cushion diamond

This 8.31ct 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 LG560236352 or 560236352. Listed at 12 retailers as of October 31, 2026, with prices from £1,008 to £7,986, a £6,978 spread on the same certified stone. Do Amore Diamonds lists it at £7,986. 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.
