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 10 retailers as of October 29, 2026, with prices from $662 to $3,604, a $2,942 spread on the same certified stone. Brilliant Earth lists it at $3,604. 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.
