This 1.44ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG780675116 or 780675116. Listed at 5 retailers as of October 28, 2026, with prices from $307 to $1,266, a $959 spread on the same certified stone. Rare Carat lists it at $1,266. 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.
