This 3.91ct 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 LG835610765 or 835610765. Listed at 24 retailers as of October 25, 2026, with prices from €555 to €3,070, a €2,515 spread on the same certified stone. Brilliant Earth lists it at €3,070. 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.
