This 5ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846656011 or 846656011. Listed at 11 retailers as of October 27, 2026, with prices from £576 to £2,906, a £2,330 spread on the same certified stone. Brilliant Earth lists it at £2,906. 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.
