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 standard cut grade and certified by IGI LG747513618 or 747513618. Listed at 12 retailers as of November 1, 2026, with prices from $1,011 to $4,261, a $3,251 spread on the same certified stone. MOH London lists it at $4,261. 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.
