This 1.3ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG850697438 or 850697438. Listed at 3 retailers as of October 30, 2026, with prices from $605 to $1,517, a $913 spread on the same certified stone. Taylor and Hart lists it at $1,517. 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.
