This 1.99ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831671612 or 831671612. Listed at 5 retailers as of October 28, 2026, with prices from $508 to $2,646, a $2,138 spread on the same certified stone. Frank Darling lists it at $2,646. 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.
