This 5.05ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG696511824 or 696511824. Listed at 8 retailers as of November 2, 2026, with prices from $1,440 to $5,506, a $4,065 spread on the same certified stone. Brilliant Earth lists it at $5,506. 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.
