This 1.55ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG739537876 or 739537876. Listed at 16 retailers as of November 4, 2026, with prices from £251 to £1,122, a £871 spread on the same certified stone. Brilliant Earth lists it at £1,122. 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.
