This 3.03ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840612390 or 840612390. Listed at 11 retailers as of November 6, 2026, with prices from $693 to $4,654, a $3,961 spread on the same certified stone. Brilliant Earth lists it at $4,654. 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.
