This 0.54ct 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 LG414059519 or 414059519. Listed at 12 retailers as of November 1, 2026, with prices from $570 to $2,835, a $2,265 spread on the same certified stone. MOH London lists it at $2,835. 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.
