This 4.13ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG619453241 or 619453241. Listed at 13 retailers as of October 29, 2026, with prices from $449 to $6,170, a $5,721 spread on the same certified stone. Brilliant Earth lists it at $6,170. 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.
