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 November 1, 2026, with prices from $404 to $2,008, a $1,604 spread on the same certified stone. MOH London lists it at $2,008. 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.
