This 1.75ct 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 LG816608070 or 816608070. Listed at 13 retailers as of November 1, 2026, with prices from $686 to $2,970, a $2,284 spread on the same certified stone. MOH London lists it at $2,970. 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.
