This 1.38ct 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 LG851653722 or 851653722. Listed at 14 retailers as of November 1, 2026, with prices from £147 to £850, a £703 spread on the same certified stone. MOH London lists it at £850. 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.
