This 3.03ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG546215433 or 546215433. Listed at 15 retailers as of November 6, 2026, with prices from $726 to $3,930, a $3,203 spread on the same certified stone. Brilliant Earth lists it at $3,930. 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.
