This 1.05ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG739543421 or 739543421. Listed at 7 retailers as of November 4, 2026, with prices from $366 to $1,195, a $829 spread on the same certified stone. MOH London lists it at $1,195. 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.
