This 1.31ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG737532260 or 737532260. Listed at 16 retailers as of October 27, 2026, with prices from $291 to $1,454, a $1,163 spread on the same certified stone. MOH London lists it at $1,454. 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.
