This 3.03ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG826624813 or 826624813. Listed at 19 retailers as of November 4, 2026, with prices from €430 to €2,601, a €2,170 spread on the same certified stone. Brilliant Earth lists it at €2,601. 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.
