This 1.28ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG754595359 or 754595359. Listed at 25 retailers as of October 29, 2026, with prices from $285 to $1,604, a $1,319 spread on the same certified stone. MOH London lists it at $1,604. 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.
