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 $3,875 to $24,750, a $20,875 spread on the same certified stone. Brilliant Earth lists it at $24,750. 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.
