This 0.55ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG850695712 or 850695712. Listed at 6 retailers as of October 31, 2026, with prices from $342 to $913, a $571 spread on the same certified stone. Taylor and Hart lists it at $913. 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.
