This 1.5ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836640819 or 836640819. Listed at 6 retailers as of November 1, 2026, with prices from $680 to $1,607, a $927 spread on the same certified stone. MOH London lists it at $1,607. 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.
