This 1.62ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG617428207 or 617428207. Listed at 6 retailers as of November 1, 2026, with prices from $723 to $2,018, a $1,295 spread on the same certified stone. MOH London lists it at $2,018. 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.
