This 1.35ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG794695693 or 794695693. Listed at 3 retailers as of November 2, 2026, with prices from $757 to $1,455, a $699 spread on the same certified stone. Brilliant Earth lists it at $1,455. 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.
