This 1.4ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846690723 or 846690723. Listed at 6 retailers as of November 1, 2026, with prices from $608 to $1,631, a $1,023 spread on the same certified stone. MOH London lists it at $1,631. 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.
