This 1.91ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG753506672 or 753506672. Listed at 16 retailers as of November 2, 2026, with prices from $313 to $2,010, a $1,697 spread on the same certified stone. Brilliant Earth lists it at $2,010. 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.
