This 1.99ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG806612143 or 806612143. Listed at 5 retailers as of November 4, 2026, with prices from $685 to $3,367, a $2,682 spread on the same certified stone. Frank Darling lists it at $3,367. 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.
