This 12.05ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG787665797 or 787665797. Listed at 18 retailers as of October 31, 2026, with prices from £2,892 to £18,472, a £15,580 spread on the same certified stone. Brilliant Earth lists it at £18,472. 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.
