This 1.27ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG787620893 or 787620893. Listed at 15 retailers as of November 1, 2026, with prices from £237 to £804, a £567 spread on the same certified stone. MOH London lists it at £804. 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.
