This 1.09ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG792621427 or 792621427. Listed at 21 retailers as of November 2, 2026, with prices from $184 to $1,064, a $880 spread on the same certified stone. MOH London lists it at $1,064. 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.
