This 1.45ct 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 LG787647793 or 787647793. Listed at 2 retailers as of November 6, 2026, with prices from $1,410 to $1,995, a $586 spread on the same certified stone. Diamond Wish lists it at $1,995. 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.
