This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG673406023 or 673406023. Listed at 15 retailers as of November 1, 2026, with prices from $752 to $3,482, a $2,730 spread on the same certified stone. MOH London lists it at $3,482. 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.
