This 2.09ct lab-grown marquise sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG844684071 or 844684071. Listed at 12 retailers as of November 1, 2026, with prices from £305 to £1,207, a £902 spread on the same certified stone. Brilliant Earth lists it at £1,207. 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.
