About this 1.28ct lab-grown marquise diamond

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 VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG775616991 or 775616991. Listed at 4 retailers, with prices from $556 to $851 at Novita Diamonds, a $295 spread on the same certified stone. 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.
