This 1.63ct 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 LG816608072 or 816608072. Listed at 14 retailers as of November 1, 2026, with prices from $574 to $2,855, a $2,281 spread on the same certified stone. MOH London lists it at $2,855. 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.
