This 1.48ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679949 or 831679949. Listed at 5 retailers as of October 30, 2026, with prices from $717 to $2,107, a $1,389 spread on the same certified stone. Brilliant Earth lists it at $2,107. 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.
