This 6.03ct lab-grown marquise sits in the over five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825604516 or 825604516. Listed at 15 retailers as of October 31, 2026, with prices from $3,434 to $12,394, a $8,960 spread on the same certified stone. Taylor and Hart lists it at $12,394. 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.
