This 11.18ct lab-grown cushion sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG723564726 or 723564726. Listed at 10 retailers as of October 31, 2026, with prices from £1,612 to £8,807, a £7,195 spread on the same certified stone. Do Amore Diamonds lists it at £8,807. 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.
