This 1.3ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG551202509 or 551202509. Listed at 2 retailers as of November 1, 2026, with prices from $455 to $1,173, a $718 spread on the same certified stone. MOH London lists it at $1,173. 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.
