This 8.54ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG750504553 or 750504553. Listed at 3 retailers as of November 2, 2026, with prices from £9,687 to £11,625, a £1,937 spread on the same certified stone. Zales lists it at £11,625. 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.
