This 3.04ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG827604371 or 827604371. Listed at 8 retailers as of November 4, 2026, with prices from $1,210 to $4,600, a $3,390 spread on the same certified stone. Brilliant Earth lists it at $4,600. 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.
