This 0.53ct lab-grown marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941507 or 407941507. Listed at 11 retailers as of October 30, 2026, with prices from $316 to $1,571, a $1,255 spread on the same certified stone. MOH London lists it at $1,571. 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.
