This 1.31ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG626412764 or 626412764. Listed at 8 retailers as of November 4, 2026, with prices from $244 to $1,750, a $1,506 spread on the same certified stone. Brilliant Earth lists it at $1,750. 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.
